Products.resourceregistries

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

- Removed the uppermost Save button from the ZMI pages for registries.
Clicking this button before the registry page has finished loading could
lead to data loss.

- Resources beginning with "http://" or "https://" are now valid and may be
included as resources. Registries will automatically disable merging,
caching, compression, and inline rendering of external resources. This
closes http://dev.plone.org/plone/ticket/8312
[dunlapm, fschulze]

- Added option to have a conditional comment attached to a given resource.
Currently the UI only supports this behavior with the CSS and JavaScript
Registries, but the underpinnings for the KSS registry is in place.
This closes http://dev.plone.org/plone/ticket/5521

- Do not try to export the `cooked_expression` into the GenericSetup
profiles. It is only an internal optimization and the value is reflected
in the `expression` value.
[hannosch]

- Store the cooked expressions as a real persistent expression object,
instead of compiling the expression on every view.
[hannosch]

- Added 'context' as an alias for 'object' in action expressions.

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

- Eggified into Products.ResourceRegistries.

- Fixed error where non-traversable resources could be registered. This closes
http://dev.plone.org/plone/ticket/8153
[dunlapm]

- Ensure that resources can be removed in xml.
[maurits]

- Purge old zope2 Interface interfaces for Zope 2.12 compatibility.

- Encode inline resources using the site encoding.
Fixes http://dev.plone.org/plone/ticket/7522
[wichert]

- Fixed potential Acquisition problems in viewlets.

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

- Properly encode the resource id. This fixes moving of resource without JS
and removing recources which contain special chars like plus signs.
Fixes http://dev.plone.org/plone/ticket/7482
[fschulze]

- Revert part of r7143: returning NotFound from a API call is never
the right thing to do since it makes the publisher show a object-not-found
page, hiding the real error. Restore the old behaviour and raise a
ValueError instead. This fixes mysterious not-found errors from
GenericSetup imports.
[wichert]

- Support Z3 template resources (not just file and image resources).
[mj]

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

- Added '/' to the strings that are filtered out in
BaseRegistry.generateId(). This fixes 7048.
[davconvent]

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

- Add support for automatic grouping mode to the GenericSetup export/import
code.
[wichert]

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

- Added a new automatic grouping mode feature. It is turned off by default.
When enabled the resources will first be sorted into groups with the same
merging-relevant settings and after that merged. In the groups the order of
the resources in the registries will be preserved.
[hannosch]

- Changed the exportimport handlers to only cook the resources once at the end
and not after each new resource has been added.
