Componentize footer

Take the elements that were all baked into all-docs-list
and inject them into the all-docs-list. This enables us to have
a separate footer component in the layout which can be initialized
without the all-docs-list viewobject.

This enables us to remove the `position: fixed` from the footer
and use `position: absolute`. Without having the element
`position: fixed;` we do not need to calculate it's width via JS
and can apply a css based pane layout.

Add nightwatch tests to work with Travis and Saucelabs
Fix initial select-all state

Sometimes it was already selected
add tunnel-identifier for Travis
Replication addon code cleanup

This is a housekeeping ticket. It removes an unnecessary dependency
on Active Tasks but mostly just contains style fixes, a little JS
rewrite and the odd markup bug fix.
Fix bulkDeleteDocsCollection errors

There are a couple of JS errors that occur when going to and from
the Views page. This just adds a check to confirm a var is really
available before using it.
Nightwatch test for Verify Installation page
Recognize manual URL changes on doc editor page

This ticket lets users manually change the URL on the doc editor page
and have the page automatically load the new doc.

Closes COUCHDB-2490
change Fauxton username variable in testing
Input field in clone doc modal full width

Just a small style fix. There wasn't enough space so the input field
in the modal now spans 100%.
New waitForAttribute nightwatch helper

This test allows us to not just wait for an element, but for an
element attribute containing a certain value. This can be helpful in a
number of scenarios, like when a JS event changes the content of a page
but the DOM structure remains largely the same (e.g. a form).
Rename index.css and require.js with md5 hash

- removes obsolete "cache buster" setting
- replaces hardcoded require.js and index.cs filenames in settings
files with for non-dev build processes with variables.
- release and couchapp_deploy tasks now rename those two files to
include their hashes, and reference them in the generated index.html
