[PATCH 0 of 6] Bookmarks improvements

[David Soria Parra]

Hi,

this is the first round of smaller bookmarks improvements for the
bookmarks in core. These are just simple patches.

One word about adding bookmarks to template styles. I have not added
bookmarks to hgweb styles as I don't know yet enough about them to add
bookmarks to it. Maybe someone likes to add bookmarks to the web templates.
That would be great.

Thanks
David
