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
Again, just want to confirm this is correct. I remove the bootstrap-specific data-toggle attribute because it no longer toggles a tab, but shows the query options tray via a JS click event.
