Additionally:

- Detection of non-virtual state inheritance
- Added a config file that allows overriding the process stack size set
by `stack-size-set!` calls
- Fix for integer multiplication with `r0`
- Fixed detection for the following macros:
	- `static-attack-info`
- `defpart` and `defpartgroup` (probably still needs adjustments, uses
Jak 2 implementation at the moment)
- `sound-play` (Jak 3 seems to always call `sound-play-by-name` with a
`sound-group` of 0, so the macro has been temporarily defaulted to use
that)

One somewhat significant change made here that should be noted is that
the return type of `process::init-from-entity!` was changed to `object`.
I've been thinking about this for a while, since it looks a bit nicer
without the `(none)` at the end and I have recently encountered init
methods that early return `0`.
