inotify: deactivate inotify status on failure workaround issue1208, add test fix traceback handling (socket.error is a singleton in this case)

inotify: fix traceback when the server has been already started

Use relative imports in inotify.server. Fixes an import failure I was getting under hgtk and hgweb: *** failed to import extension inotify: 'module' object has no attribute 'inotify'

a socket error might be a tuple or a singleton

Fix for Issue1260

highlight: only pygmentize for HTML mimetypes For non-html mimetypes it doesn't make much sense. This also fixes the issue that highlight unconditionally adds a <link/> tag for its CSS to the template's header (which is pointless in text/plain output).
