0.13.0

Features

• Added scenarios (doesn't save personal records yet)
• Custom game versions now show in the game selector dropdown (e.g. games/BAR.sdd)

Fixes

• Fixed lua table -> JSON parsing which was causing some AI options and scenarios to break (added a unit test for this too)
• No longer attempts to redownload game versions that are already installed

Other

• Default game version is now hardcoded into the lobby and will need to be updated manually
