This decision was made to reduce the complexity of using .include whilst
juggling with tools/scaninc and tools/preproc:
- tools/scaninc doesn't apply the proper search rules for .include (it
  assumes #include behavior). In particular, it doesn't consider paths
  starting from $PWD, and doesn't scan the included files as a result.
- .include had to be processed before #include by preproc in many cases,
  as code was being included that had to be preprocessed by CPP (think
  of #define). This contradicts standard GCC behavior.

To make include paths consistent across the asm/ data/ and src/
directories, the following files were moved:
- constants/ → include/asm/constants/
- asm/macros/ → include/asm/macros/
- asm/macros.inc → include/asm/macros.inc
- include/macros/m4a.inc → include/asm/macros/m4a.inc

As part of the necessary changes for this to work, the scaninc method in
the makefile was improved to generate .d files that don't choke when
files are missing.

* death by 74 files

* 20% reached

* doc move stuff in pokemon

* fix undef reference

* doc more and plumb a few more constanst for num party members and num moves

* that struct is def PokemonMove.. clean up all code with it

* more data dumping and some code cleaning

* split out cutscene scripts

* initial start at script conversion

* more script work

* use correct type

* clearer up struct field names

* split known scripts into seperate files

* no need to preproc pure ascii strings in debug

* more cutscene work

* split out personality test scripts

* solidify text macros and doc some dungeon fields

* more scripting work

* decomp/doc cpu funcs and gpu reg funcs

* use Cpu32 macro funcs

* address review comments

* decomp SetBGOBJEnableFlags
