Move all the source files to 15-character ProDOS-compatible file names.

Dmake gets confused if you use over-15-character file names, so they needed to be shortened to get it to work. While I was at it, I also switched _ to . in the filenames so they're fully ProDOS compatible.

The shell/hush_test directory (not needed to build the code) still uses ProDOS-incompatible file names.
