Decompile RIC func_801719A4 (#827)

This is a pretty big function, and I'll admit that my code for it is
pretty low quality. But it matches. Scratch is here if you'd like to
make improvements:

A lot of the things that I tried to remove the gotos and temp variables
didn't work.

The entity extension for this uses f32 variables. Those are defined in
`game.h`, but `game.h` is not accessible to `entity.h`, so I moved the
definition of f32 to `types.h` which is accessible in all places and
overall seems like a better place for it anyway.
