Changes

Tree: Redo bans, Make sending packets memory safe and tiny things

This is a big one.
So lets start with bans. Bans have been completely refactored.
We no longer use txt file but json file for easier searching
and etc.
This also allows us to write what we want into them.
This also include WIP CIDR ban support. (Not working yet)
And also allows us to do range bans which will come later on.

Bans now also include reasons and timer.
Timer is not utilized yet as we only have perma bans for now
but that will change soon.

And most sending packets did not check if the packet actually
succeeded sending. This would cause memory leaks.
Which is def not something we want.

Also move ip functions into its own file in Utils.

I might have missed something but i think thats it.

Commands.c: Remove LOG_DEBUG left over from debugging
 (commit: aac8e13)

Gamemodes.c: Fix float lost accuracy

Instead of having possible errors in there lets
round it down just to be safe

Source: Simplify looking for banned users
 (commit: 314b6af)

Server.c: Use host IP instead of the one in ban string

When CIDR and range ban support is in we will want to use
the host IP instead of the one in ban.
 (commit: 6bd5d25)

Packets.c: Change message delay to 400ms

Still enough to catch spammers and yet enough to allow fast typers
 (commit: 21bff23)

Server: Add initial CIDR & Range ban support

Now we can ban CIDR ranges with /banip <ip/CIDR> <reason>
And range with /banrange <startRange> <endRange> <reason>

These are initial support and improvements will come soon
 (commit: 71f62dd)

Server.c: Handle disconnecting banned players properly

If banned player tried to join we would get in a lot
of trouble as soon as they disconnect cause we would
try to send a lot of stuff that depends on PlayerID.
Which these players do not have.
Causing overflowing of variables and other mess. Handle
it properly.

Source: Big ban changes (Read description)

Newly introduced commands:
/hban - 6 Hours ban
/dban - 1 Day ban
/wban - 1 Week ban
/mban - 1 Month ban
/pban - Permanent ban

/banip has been renamed to /ban

All ban commands excluding range now also support
either IP ban or #ID ban.

/ban can now be used to also optionally set
the amount of time in minutes that the ban will last.
Same applies to /banrange

All of this combined i think makes it pretty much possible
to ban anyone you may. Range bans, CIDR bans, Single IP bans.
Up to you. All with time.

Keep in mind when setting permanent range bans the time
is not 99999... It is 0 for permanent ban.

Server: Unify xban commands
 (commit: 6cc7b6f)

Commands.c: Unban support and ban fixes

Now we support:
/unban - Unbans the specified IP
/unbanrange - Unbans the specified range
/undoban - Reverts the latest ban

/unban takes only 1 argument and that is the IP to unban.
/unbanrange takes 2 arguments and those are start of the
range and end of the range to unban. Start and End range must be
exactly the same that was banned.
 (commit: 456a9f3)

Commands.c: Error out with user specified IP in /unban
 (commit: 8271b22)

Commands.c: Use Util/ prefix for JSONHelpers include
 (commit: 765eb01)

Server: Colorized terminal output & small fixes
 (commit: e017ed6)

Types.h: Make LOG_DEBUG purple

The colors would match too much with others
making it hard to see debug messages.
 (commit: c55b069)

Source: General cleanup

get_nanos was defined multiple times as static
Physics had to be split to C/H files in order
to prevent nasty includes
 (commit: c338a91)

Protocol.c: Optimize checkNode

Previously we had to go trough entire array to check
if node was already visited.
Replacing the array with 3D array and checking using that
saves incredible amount of time.
 (commit: 850b1a2)

README.md: Some small details
 (commit: ff3169f)

Source: Revamp most logs and messages
 (commit: c677e4a)

Source: Add server console

Server console is a console
that server administrator can use to use
commands without being actually connected
in game.

For now the console includes also
history of commands preformed during
that session of the server.
Meaning when you stop the server
history will be cleaned.

Tab completion will be implemented
later on.

Tree: Resize map memory to the exact VXL memory size

Before we would output memory to 10MiB regardless
of the actual memory size.

Most of the time we would fit in this size but its
easy to hit this limit with much more complex maps.
Now we allocate the maximum possible memory size for
given XYZ size of VXL and after filling this memory
with the map info reallocate to the exact map size
of the output VXL memory. And compress that.

This has multiple advantages.
Its impossible to overflow if given valid VXL map
info about the size.
We send the minimal amount of data to player so
faster map loading and compressing.
We can load any size of valid VXL map. Even those
that may be currently non existent. Such as
1024x1024x256.
 (commit: 8236b4e)

Map.*: Add protection against loading bigger map then allocated memory
 (commit: a8e047d)

libmapvxl: Update libmapvxl

New commit makes returning of size thread safe
