Redmine

This is the beginning of a patch to add "Delete" to all but the most recent version of the wiki history list, this cleans up the history - without the mess of "destroy" then adding back the page.

This isn't a complete patch; I'm just starting picking up ruby, and aren't sure of the next step; can someone help a bit?

I got as far as wiki_page.rb delete_version. This takes a version number and correctly does find_by_version, but how do I destroy the passed version?

Thanks for the help.
