add findKeys method for CouchDB

[Hiswe]

Hi,

I'v added the findKeys methods for being able to use the listAllPads methods of Etherpad.

Also the felix-couchdb was missing in the package.json.
And about felix-couchdb, it was also broken for me… so I made a pull request in order to make it work. Without this patch, this module will sadly throw errors 😞

Afaik this should not be how it's done.

:S
I'm not a couchDB expert at all ¬_¬'
But I haven't seen any way to filter by a dynamic regexp in a design document…

I might look it further, but being in a hurry I can't do it right now.

Adding findAllPads to the module is wrong. findAllPads is a method exclusive to Etherpad.

That logic needs to be in Etherpad and not ueberDB :) Make sense? Look at the other modules for ueberDB, you will see they don't contain findAllPads

You're right 👍
Trying to make Etherpad working, I haven't seen this huge flaw.
I really have to figure out to put a regexp in the design doc…
