[Owncloud] File editor testing

[Tom Needham]

Hi All,

So I haven't been around here too long but would just like to say what a great little project this is!

I have decided to get stuck in and have implemented Ace Editor. Just like the old text viewer, files can be edited by clicking on them in the file browser. It is available in a new branch 'ace-editor' and would appreciate it if I could get some feedback on it. Martin (h3ik) has helped me squash some more bugs this afternoon but if we want to get this out in 2.0 then it needs to be rock solid. 

Thanks,
Tom
