Decomp btl_are_all_enemies_defeated (#337)

Browse Source 
* Initial decomp

* Rearrange variable definitions and if-statements

* Getting closer to matching

* Only address matching left

* Rename variables for clarity

* Search and replace was too eager...

* Rewrite as a for-loop. Matches!

* Removed and renamed variables

* Rearrange statements for neatness. Remove unneccessary comments

* Ran coverage

* Change the typing to Actor*

* Rename variables, don't be so literal with return values, and compare pointer to NULL, you dunce

* Move variable definitions around
