Almost done:
- `target-handler` (`(none)` event handler casts and CFG error)
- `target2` (`(none)` event handler casts)
- `powerups` (`cloud-track` does some weird stuff with `handle`s)
- `gun-states` (CFG error)
Some progress in:
- `water-flow`
Additionally:
- Clean up the two year old Jak 3 config file and add a config skeleton
(disassembling seems to not have worked, but I was able to dump obj
files and the `all_scripts` file)
- Fix automatic skelgroup detection and `defskelgroup` macro for Jak 2
(closes#1950)
- When a function decompiles without any major errors, a warning is
generated with the op id for each unresolved load and store that will
likely fail to compile (closes#1933)
