Slightly better looking file actions. 

We discussed this as an interaction fix here : https://github.com/owncloud/core/issues/202
Takes out rename from the fileactions.js and makes it look better.
The approach is sort of hackish but couldn't find a better way. 

Big thanks to @Kondou-ger for the help!
