unbelievable amount of strcmp() calls (25 million) due to the list searching.
This has been reimplemented with a set-intersection scheme, due to the fact
that file lists are always ordered. - NEEDS TESTING
* Minor clean up, "globalized" the str_cmp helper to match the alpm comparison
signature, so we can use it elsewhere.
* Makefile targets to rebuild po files now work - use 'make update-po' in
the po directories.
* Added two new translation templates as requested on the ML- 'it' and
'pt_BR'.
This commit might be a bit big for the mailing list to like on the commit
message. :)
