Changelog below:

• Lighting system overhauled.
• Lots of blocks interact correctly with lighting now (stairs, slabs)
• Few sound tweaks
• Fixed witch being white for some
• More bugfixes & slight tweaks!

Some bugs have been reported and there might be another "b" release soon... according to @Dinnerbone:
"So farmland is broken. Okay, that's a start! Yay mass testing. Also stairs are darker than you'd expect but that's three characters to fix."
