[Coquelicot] Some patches

Hi

Recently I found time to track down a file descriptor leaking bug in coquelicot that annoyed us for a while. Essentially at least every 404 leaked some FDs on the @path/.lock path.

Attached is a patch for a spelling typo, making it possible to allow multiple stylesheets, which makes it easier to customize the look&feel and the patch to fix the leaking FD.
