New _m() gettext wrapper with smart detection of plugin domains. Plugin base class registers your gettext files if present at initialization.

update_pot.sh replaced with update_po_templates.php which can do core, plugins, or all (default).
Top-level Makefile added to build .mo files for plugins as well as core.
