OAuth support

[Abbe98]

OAuth support would be very valuable, especially for users with Two Factor Authentication enabled.

I agree and this is something that would be useful for my tools, but this is currently not on my radar. I need to kill off all the non-API using methods first.

The last method using base was rewritten in 18aaaf9. The next blockers are swapping apiUrl and query for ConcurrentHashMaps (soon) and JSON support (JEP 198).

Instructions: https://www.mediawiki.org/wiki/OAuth/Owner-only_consumers (the more complicated flow can be left later).

The OAuth signature needs to be computed at the last possible moment, immediately before connection.connect() in makeHTTPrequest. OAuth is a MediaWiki extension, so it doesn't belong in Wiki.java. That makes the solution ugly. I'd recommend using bot passwords for now.

All HTTP GET parameters are now in the same format as of 56a923f .

That's sad.
