[PATCH 13/18] gitweb: Add commented url & url hash to page footer

["John 'Warthog9' Hawley" <warthog9@eaglescrag.net>]

This is mostly a debugging tool, but it adds a small bit of information
to the footer:

<!--
	Full URL: |http://localhost/gitweb-caching/gitweb.cgi?p=/project.git;a=summary|
	URL Hash: |7a31cfb8a43f5643679eec88aa9d7981|
-->

The first bit tells you what the url that generated the page actually was, the second is
the hash used to store the file with the first two characters being used as the directory:

<cachedir>/7a/31cfb8a43f5643679eec88aa9d7981

Also useful for greping through the existing cache and finding files with unique paths that
you may want to explicitly flush.
