Super lazy fix for allowing subfolders.

Right now it's more important for me than it being right, or even for it
being mantainable. Take that future Edwin!
The laziness cannot be stopped
Allow subfolders, fudge with bracket placement

Ignoring the sketchy stuff done in the wiki parser and the XLST page I'll need
to fix later, we now can create Wiki entries in sub-folders. We just create
non-existant folders now. That's about it.
