Added the ability to rename existing pages.
[[!redirects Some Page Name]] redirects Wikilinks [[Some Page Name]] to
the current page (assuming "Some Page Name" does not exist).
Real pages trump redirects (though this may change, depending on
user feedback).
Dunno why this was buggered again. ":back" doesn't seem to function as it used to.
Also, when uploading a file from page "foo", it's important to return to "foo" after
a successful upload, rather than redirecting to the HomePage.
Finally, a favicon tweak.
Update dnsbl_check plugin to latest version.
Update Maruku to latest version.
In the wiki_controller, only apply the dnsbl_check before_filter
to the :edit, :new, and :save actions, instead of all actions.
This makes mundane "show" requests faster, but does not
compromise spam-fighting ability.
Start work (which may not pan out) on a new sanitizer. Right now, it passes
all but 1 of the HTML5lib Sanitizer's unit tests. But it doesn't do much
of anything to ensure well-formedness. This is not an issue for Maruku-processed
content, but it is a concern for <nowiki> blocks.
(One solution would be to use the HTML5lib parser on <nowiki> blocks.)
In any case, this baby is 3 times as fast as the HTML5lib sanitizer.
Apparently, the form_spam_protect plugin only works with HTTP POST, not GET.
Unsafe operations (save and file-upload) should be POSTs anyway.
Fixed.
Also, two broken tests fixed. Only two Unit Tests now fail: both are minor bugs in XHTMLDiff.
