Products.resourceregistries

------------------

- Comment out views from old resource registry so it does not render
them on Plone 5. Meanwhile we don't remove the product. It is
planned to be removed on Plone 5.1.

------------------

- Use ``application/javascript`` instead of ``application/x-javascript`` for
the ``Content-Type`` http header of JavaScript resources. Also see:

- bugfix: do not convert URIs such as
url(data:image/svg+xml;base64,PD94bWwgdmVyc2lv) to absolute urls

----------------

- add csrf token to delete urls for resources

- Properly handle redirections from login view; resources used to be erased
on authentication redirect for POST action

- Replace troublesome HTTP_REFERER redirects, they can lead to infinite
redirects on expired session re-login

- Don't try to traverse to remote objects starting with '//', triggered
from plone.css

------------------

- Allow users to add resources starting with '//', the proper way to link
to external resources when serving over http and https. This makes it
much easier to manage content on CDNs.

------------------

- Avoid recursive call of _migrateCookedResouces method in BaseTool which
prevented the old concatenated resource storage from beeing migrated.
The problem emerged when migrating from Plone 4.2 to 4.3.

- Fixed some spurious test failures for Expires being off by
minus one second.
