Rmk99 cleanup display fonts (#2203)

All display fontfiles are now in the single fonts/displayfonts/ directory. The subdirectories adobe, big, other, altofonts have been deleted, and are no longer on DISPLAYFONTDIRECTORIES. The few additional displayfonts from the envos repo are included.

This is the result of:

Removing all byte-identical files, leaving a representative of each such equivalence class in displayfonts/

Removing all files in displayfonts that are renamed byte-identical copies of other files in displayfonts/ (e.g. helvetica1-MRR-c0.displayfont is a fake-renamed copy of helvetica4-MRR-c0.displayfont). These are to be constructed on the fly by the font substitution mechanism.

Roughly comparing the bitmaps of non-identical files with the same font family/size/face/charset in the different subdirectories, and making displayfonts/ have the one that looks best (e.g. most glyphs, unless garbage), giving priority to ones that are already in displayfonts/.

Moving the remaining odd-ball files from the subdirectories to displayfonts/ (e.g. gates, music).

Copying from Envos the 30 or so files that are not byte-identical copies of files already in displayfonts/.
