Version 0.2.0 released

Today marks the release of version 0.2.0 of WinWar. Although there have been many minor changes, refactorings and lots of other stuff, the main purpose of this release is to support the demo version.
(wowpedia still has a link to it here: http://wowpedia.org/Warcraft:Orcs%26_Humans_%28Demo%29)

Just take the DATA.WAR from the demo and put it into the Assets/Data folder.

The next releases focus on actually making the game playable:
- Finish the ingame UI
- Finish the low-level AI
- Add victory conditions so that you can play campaigns
- Add resource harvesting and constructing buildings/units
