- Revision ID: edam@waxworlds.org-20100704144448-1m30v811opup20fs
- got rid of the pretend ImportContacts activity alltogether (and made the Intro activity the startup one)
- massively simplified the WizzardActivity class so it works propperly
- moved all code to org.waxworlds.edam
- added an "aborted" message when the importion is aborted
- simplified the 3 actions the worker thread can take when stopping (only 2 were actualy used) to "aborted" or "alldone"
- changed intro message to match website
- bugfix: don't blow up when the My Contacts group is missing
