Automatically select the default key for the current server when doing actions.

This commit introduces automatic selection of the default TSIG key for all
available actions (add, delete). For enabling that it has been necessary to
provide the whole BindServer object to the template, which caused some
additional changes.

I also took the opportunity to unify some styling (indentation, linebreaks) of
the HTML templates.
