Subject: more placeholders for namespace templates

This patch adds a @FILE@ placeholder for namespace templates which is similar
to the @PAGE@ placeholder but keeps underscores intact. It also adds
placeholder to insert the page name with a first uppercase character, all words
uppercased or the whole string uppercased.

The utf8 library was enhanced with utf8_ucfirst and utf8_ucwords functions
