Add an un-spaced line number to the filerevision line generator.

In OpenCM, every line number in a displayed file had an anchor. The
URL
   .../path/to/file#22
would take you directly to line 22. This was useful, as it allowed us
to reference particular locations in file versions directly from the
URL.

At present, the lines() function within filerevision() generates a
line number that is pre-biased with some number of spaces (a pre-bias,
aside, which should more properly be decide by the template if that is
possible). Because this string has leading spaces, it cannot be used
as an anchor target.

This change adds a new element "rawlinenumber" that provides the line
number *without* the spaces, so that anchors can be generated in the
template.
