Minor bugfixes

Made error messages when the mod can't load a saved setting more clear.

cleaned up sound code, added 6 more sounds

v1.1 introduced the options menu, plus some experimental performance options. This will likely be the last major update.

v1.0 introduced glass shattering when it is hit, rather than using a keybind.

Original proof-of-concept version; glass only broke when a keybind was pressed
