i18n Again

I've updated the Locale Package again, only some minor changes superficially, but with a significant performance improvement and adding a check for true static pages (those handled by the pages controller).

The todo list for the locale package is quite short:

• Add gettext support
• Add DB option
• Provide means of chosing which method of storage/retrieval to use

Time is of a premium lately, and I only develop things as and when I need them. If anyone has suggestions or requests regarding this package please leave a comment.
