More unused stuff removal (#49)

* More unused stuff removal

delete:
- giant 'metaheaders' (JA2 All.h, Laptop All.h, etc), preferring to add #includes directly where needed
- unused ExceptionHandling and DbMan translation units
- unused WizShare.h, Bitmap.h, trle.h, video_private.h headers

* remove mentions from vc proj files too

* remove preprocessor conditionals for unused definitions

find . -iname '*.h' -o -iname '*.cpp' -exec unifdef.exe -m -UPRECOMPILED_HEADERS -UJA2_PRECOMPILED_HEADERS -UWIZ8_PRECOMPILED_HEADERS -UPRECOMPILEDHEADERS {} ';'

then manually fixed a couple files the tool errored out on

* yes, the comments too
