Comment the makefile.
Reorganize makefile targets for clarity.
Remove inline comments in an object recipe.
Add image suffixes to the makefile.

Explicitly define png dependencies (none).
This keeps make from looking for nonexistent dependencies with extensions like ".png.o".
This doesn't make it go any faster, but it at least makes debug easier.
Combine poke%.gbc build targets into a generalized one.

Now only one target is needed for all versions.

$$* also works instead of %, but in a pattern rule % is probably clearer.
Add a comment to the "compare" target.
Commented function
- Named and commented Func_4c70.
- Removed gfx/diagonal_lines.png, which is not actually graphics.
Labelled many functions/variables
