Addresses for GNUstep

This release fixes a most annoying bug which
caused version 0.4.5 to output broken database
files when used with recent GNUstep CVS versions.
Subsequent starts would complain about
GSMutableString not recognizing "-count" and would
die shortly afterwards. This problem was fixed and
the old, broken database files are automatically
corrected. In response to this breakage, version
0.4.5 has been made unavailable, and it should not
be used anymore. A new Spanish localization was
added. A couple of minor bugfixes were made.

Many more quirks and small UI bugs were fixed. It
should behave quite as expected now.

This release fixes a segmentation fault on some non-x86 systems. It also fixes a bug that caused GNUMail to come up with a new email window when editing a person's email address.

Drag and Drop support has been rewritten, unified and greatly enhanced: people and properties can now be dragged from almost anywhere to almost everywhere. A new Goody has been added: VCFViewer, a GWorkspace inspector for VCF files. This allows looking at the contents of VCF files prior to importing, and even dragging entries out of VCF files directly into AddressManager. The View classes have been cleaned up, and some more bugs have been fixed.
