gitweb: use monospace font for commit messages

gitweb: use monospace font for commit messages

Commit messages often contain vertically aligned text. The default
paper style already uses monospace fonts for rendering commit messages.
And, AFAICT, a number of Git servers also render commit messages
with monospace. It seems like the reasonable thing to do.

This commit converts all instances of the full commit message
in the gitweb style to render with monospace.
