* Remove nsFileSpec from Address Book - almost complete (see [https://bugzilla.mozilla.org/show_bug.cgi?id=132180 bug 132180]). This is really a tidy up to the backend so that we're not using obsolete code.
* Remove nsDirPrefs.h and nsDirPrefs.cpp - they are a real mess and get in the way quite a bit.
* Address Book autocomplete transfer to toolkit (WIP)
* VCard - we need to either rewrite this or find a decent library.
