Recent-changes are in, rst is activated.

Only question:
What default markup language for new pages.
(Can be adjusted)

[ ] keep it as it is (Moinmoin)
[ ] creole (suggestion by Bernhard)
[ ] rSt (suggestion by Ralf)

One problem is that if we change the default, we would need to mark
the current pages to be moinmoin Markup.

@John, as the primary wiki author in recent month, which markup option
would you prefer?
