i18n: let Makefile generate hg.pot and xx.mo files

The target update-pot runs extracts strings using pygettext.py and
updates po/hg.pot. The translators can then use msgmerge to merge the
new strings in hg.pot with their xx.po file when they want to.

The update-mo target generates a locale/xx/LC_MESSAGES/hg.mo file for
each po/xx.po file present.

The MANIFEST target now also depend on update-mo and includes the
hg.mo files.
