Renemed all variables to fit into a namespace

Basically, all Toy varaibles, functions, etc. are prepended with "Toy_",
and macros are prepended with "TOY_". This is to reduce namespace
pollution, which was an issue pointed out to be - blame @GyroVorbis.

I've also bumped the minor version number - theoretically I should bump
the major number, but I'm not quite ready for 1.0 yet.
