- added new certificate format in ConfCertDialog and ConnectFriendWizard, with a button to switch to old format if necessary

Browse Source 
- added automatic cleaning of certificates in both formats
- grouped all certificate cleaning/parsing code in rscertificate.cc
- removed unused files cleanupxpgp.h/cc
- added upper/lower case to rsid template.

The new format is to be tested. It is supposed to be much more robust than the previous format,
in particular, allowing any string for location names.
