Merge pull request #1 from bolt/master

Merge with HEAD
Adding the filelist contenttype: backend naive approach.
Tweaking the ImportWXR extension. Way less memory-overhead.
Okay so I got this to work!

.... but this doesn't make it pretty!
We'll provide, just like imagelists, a placeholder image along with a
changeable description. Another thing to, maybe, provide might be a
filesize. But as the files are static on the server laying around as
files, I think their output may be read from another place and should'nt
lay around within the DB.
Removing "The Stack" (use from server) for filelists for now.
And some frontend styling 'n' stuff.

I can somehow feel @sspringer82 punching me for this...
