Port View Indexes work from PR #33

This is porting over some of the work done in #33 around indexes with some modifications

Here are the main changes:

 - the select-all buttons + bulkdelete are now in the right-header / header / apibar area
 - the documents are styled different
 - indexes got an own module where we can add "lists & freinds" in a later step
 - we got a two-pane layout for creating indexes with a nice couchdb watermark. there is no preview implemented yet, but we can do this in a later step
 - when you open an existing index, you will get a nice view where you can modify the current design doc and then save it as a new index on the left side and you get the current results on the right side
We don't need the api bar in the right header any more. We worked to move this out.
