Changelog for 2.3

[Kildor]

I`ve started to rewrite current changelog, and currently I think about different organization of changes.

Here is my idea:

* Coding (in general)
* UI
* Battlescape
* Geoscape
* Campaign
* Base
* Inventory
* Research and UFOPaedia
* Maps
* Artwork in general

May be there will be some other categories. Does anyone have other ideas and suggestions concern this valuable part of the release?
May be UGV (but they aren`t finished)? Models? What else?

Sounds? Since Gren has been doing a bunch on that front.
