Garry's Mod Moonscript v0.6.0

Initial release! Complete with the following goodies:

• Automated builds for both Windows & Linux (moon & moonc only for now).
• :: as an alias of \ for function chaining and self-passing function calls:

obj::func()
obj\func() -- equal

obj:func()
obj:func()

• Bitwise not (~) is now compiled as a bit.bnot() call. Further bitwise additions soon!
• Fixed moon & moonc argument parsing issues on latest moonscript master.
