Replaced the linear numbering of getUnique<blah> functions
(which counts up from 1 to find a free file name) with a call to
uuid.uuidv1.

This provides unique GUID tagged entries which allows synchronizing
~/.local/share/applications files more easily between two computers.

Instead of:
alacarte-made-1.desktop

we get:
alacarte-made-aa49738a-2ac8-11e2-869b-1c6f65c8b78b.desktop

Both are functionally the same to the end user, but easier for
synchronization purposes (i.e. with rsync or Unison) since name
collisions are avoided.
Eliminate search delay, to prevent incorrect app launches for fast
typists.
menu applet: remove mainloop call for _doSearch, remove some other needless
stuff.
