Update CEGUI

[Pirulax]

Is your feature request related to a problem? Please describe.
So, CEGUI is a littlebit outdated(just a tiny bit. It's version 0.4 here, and the newest one is 0.8.7)

Describe the solution you'd like
Updating CEGUI would solve the problem, since the newer CEGUI has some neat features, which could solve the need of custom dx libs like dgs.

What kind of features would you like to see from a CEGUI upgrade?

@qaisjp I'm gonna hit you with the huge one as an example - XML layouts :)

It would be pretty amazing to see some recent version of the CEGUI, but sadly it is a bit too late for that. It hasn't been regularly updated over the years and there are metric butt tons of incompatibilities between versions of the lib itself + there were also some customizations and fixes made by MTA devs back in the days and it may complicate things a bit. The upgrade is not impossible, but for sure it's gonna be challenging and very time consuming process.

It has a lot of bugfixes, new thing(like what @4O4 said)

High flexibility, you can code your own widget renderers, use your chosen XML parser, script module, etc...

CEGUI 1.0 is set to support multi-threading so in case you decide to wait a little bit longer, it would be nice to have it running on a separate thread. There will also be some major changes to their API so I would suggest not to hurry with implementing 0.8.7
