Optimized Page Titles

This is a patch that will tweak phpBB's page titles. It aims to correct the page titles in phpBB to be more search engine friendly and bookmark friendly.
• When viewing forums, forum names come first, followed by the site name: Current Forum - My Site Name
• When viewing topics, topic titles come first, followed by the site name: Current Topic - My Site Name
• The 'View Forum' and 'View Topic' text is omitted from the title.
• This will also add Page Numbering to paginated forums and topics, (this idea/code inspired from a MOD by Greenweaver and Evil<3): Current Topic - Page 3 - My Site Name.
• The use of bullets are replaced by hyphens, so there are always only hyphens between title subjects
• All other pages like UCP, MCP, etc will display the page title the way phpBB has in the past, except using hyphens instead of bullets

A GIT format-patch file is attached with the changes to do this.
