Slowly attacking on all the points from the 0.5.4 QA
report, so this release adds sound! Just place either wav, ogg or
mp3 short sound in the root `audio/` folder.

The new `oncharaover` and `oncharaleave` now should allow
implementation of interesting puzzles triggered by pushable
charas or charas that are lured by the player. Also `onleave`
should allow triggering actions when the player chara leaves
a tile (like releasing a previously pressed floor button).
