EMC 2.2.1 released

As with any .0 release, there were a few egg-on-face mistakes. The ones we know about have been corrected in 2.2.1, now available from the regular places:

fix packaging of stepconf.glade

german translation improvements

package additional new-in-2.2.x programs (pumagui, scaragui, hexagui, tracking-test, teach-in)

fix problems using v2.1 var file -- it's silently upgraded with the new entries used by v2.2 instead of issing weird errors at startup

fix problem with probe_parport on certain machines

fix problem with non-integer INTRO_TIME
