Remove Windows nightly variants for different gfx backends, and other nightly changes

The 5 remaining Windows nightly builds are:
 music_sdl, music_native, music_native2, music_silence, music_sdl-debug
plus the installer.

Also changed the naming scheme for nightly builds from eg.
 ohrrpgce-wip-directx-sdl.zip
to
 ohrrpgce-win-music_sdl-wip.zip
This is much more consistent with other builds

Also, remove a redundant rebuild of unlump, relump and hspeak, and build them
with gengcc=1 debug=0, just like custom and game (doesn't affect hspeak).
This wipes 1.5MB off the size of relump.exe, a nice decrease in download sizes!

Also some cleanup.
