git-remote-mediawiki: add preview subcommand into git mwbp/mediawiki-preview

In the current state, a user of git-remote-mediawiki can edit the markup text
locally, but has to push to the remote wiki to see how the page is rendererd.
Add a new 'git mw preview' command that allows rendering the markup text on
the remote wiki without actually pushing any change on the wiki.

This uses Mediawiki's API to render the markup and inserts it in an actual
HTML page from the wiki so that CSS can be rendered properly. Most links
should work when the page exists on the remote.
