Test server and two small updates

Update: now on the new domain!

Hi everybody! In light of opening the client code for contributors, we've decided to also set up a proper test environment. If you want to be the first to see new features and to help us make sure they actually work, welcome to https://atwar-game-test.com!

Test site uses a test service and test database, so everything is completely separated from the live site. You will have to create a new account, as your old account password wouldn't work (privacy concerns!). We'd also advice not to use the same password you're using on the live site.

There are currently two very small updates there, courtesy of Safari and Clovis:
- Saving your preferred color. When entering a game and selecting color, it should be automatically preset the next time you enter the game (if not already taken). The preset gets erased when you close your browser.
- Bug fixed: after merging air units with land units correct range should now be displayed.

We've tested these already and they seem to work, but feel free to give them a go.

These updates are baby steps for now, as we still don't have a resident programmer. Having a proper test enviroment will really help to get things going though, as it's always a very time consuming part of the development process.

Cheers!
