Version 3.0

So v3.0 shouldn't have too many bugs it in, if any at all. I forgot to add nobat.png to the last release, but I made sure to add it before shipping this time.

This release is also the first release to actually include an INSTALL file, I guess that's kinda note worthy.

Anyway, I hope that everything builds and runs okay, but if it somehow doesn't and ZBatt segfaults or something, I have a gif for that, enjoy :P
