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.
Reduced test duration by a factor of 11,000. Don't ask.
Also, something funny is going on with the time headers, so I
stuck them into source/toy_common.h, I'll figure it out later.
