Prototype 0.2

Quite a lot of new things have been added:

• More options for the random battle.
• The beginning of a campaign mode (with placeholder graphics for now).
• A screen for managing your squad.
• 32 unit abilities implemented (up from 16).
• 57 units (up from 18, although not all of them are currently used).

Implementing the squad screen taught me a lot about using Ren'Py's screen language. I think for the next version I might try rewriting the battle screen in a similar way. It would make it less prone to hang or trigger Ren'Py's infinite loop detection and make it a lot easier to test and debug unit abilities. The reason I didn't do so initially was because I wanted all of the battle logic in pure python, to make it easier to switch interfaces. Using screen language would mean re-implementing the main battle loop in Ren'Py rather than python.
