Support custom xmlrpc endpoint for MoinMoin wiki

[psss]

Resolves #239.

This seems to be working fine with the new RPC2 endpoint provided by @mrc0mmand. Example config:

[wiki]
type = wiki
api = RPC2
wiki test = http://the.wiki.server/

@AsciiWolf, @optak, please give it a try and let me know if it works for you. Thanks.

@psss It seems that wiki.brq does not support RPC2 so I had to comment it out in did config, however it works fine with wiki.test. Thanks! :-)

Yeah, I wasn't sure if this will be the final solution, so I haven't reconfigured the BRQ wiki yet. Will do that next week.
