Title: external links should use underscores instead of spaces

Previously:

Input: [[Foo Bar]]
Output: Foo Bar

Now:

Input: [[Foo Bar]]
Output: Foo Bar

Note that the relevant part of the spec:
http://wikicreole.org/wiki/Creole1.0#section-Creole1.0-LinksInternalExternalAndInterwiki
gives examples that show this behaviour.
