Raspberry Pi JS Joust

Recently there may have been some crashes when running games with 10+ players. Recently a stability update was added which should allow 18+ players to play Joustmania reliably without it crashing.

A whole range of updates have been added to Joustmania. USB soundcard is no longer required. Mp3, flac, ogg and other sound types are now supported, lots of other improvements and enhancements to gameplay, functionality, and the webui!
