I checked in a basic version of the long promised "auto-wikification" button
on the edit page.
Features, as of now:
* <b> and </b> are replaced with '''
* <i> and </i> are replaced with ''
* <h2>, <h3> and <h4> are also converted to === style
* It fixes [[broken] links
* It converts [[self-links]] to self-links
* It removes [[talk:pages|talk]] and [[talk:pages]] (only for that page!)
* It simplyfies [[plural|plurals]] to [[plural]]s
Also, it leaves text in <pre> and <nowiki> tags alone.
Please, check it for bugs, and add some features!
