dist: new application icons and Makefile

Continuing the discussion started on GitHub over
2014-09-30T01:33:29Z!mikeonthecomputer@gmail.com, all desktop entries
now have unique icons. Keeping my own personal bias, stfkill3 is still
used for FreeDM, but the Debian choices for their own distro are used
for Phases 1 and 2.

Also, the icons are actually generated automatically now.
