this was, I guess, an attempt to provide users with an easily accessible ibar icon when starting a new config. problem: xterm isn't installed by default on ANY distributions! so now we end up providing a launcher which is guaranteed to fail, and that makes us look pretty stupid. same thing goes for mplayer.
regardless of whether they're installed, however, these aren't our apps, so we shouldn't be trying to provide .desktops for them: doing that tell users that we support and recommend the use of these apps, and I'm not prepared to make that claim for any app other than powerpoint.
it can open files using XDG specification, including defaults.list
(~/.local/share/applications/defaults.list and
/usr/share/applications/defaults.list) and mime type handlers known by
your system.
Now we should get xdg people to detect enlightenment and call this
binary.
