BUG Correct wrong parameter order.
FIX: use standard template rendering process for RSS feeds

This changes the behaviour of output to browser to use the standard SilverStripe rendering process rather than an echo statement to enable easier testability.
BUG: augmentSQL always extended on base data class on query finalization

The augmentSQL DataExtension method is always extended on the base data
class of data objects in DataQuery::getFinilisedQuery(). This results
in augmentSQL not being called for extensions that are applied to non-
base data classes when finalizing the query.

For example, if Versioned was applied to class B which extends class A,
which in turn extends DataObject, then augmentSQL would be extended for
class A in DataQuery::getFinilisedQuery(). Since class A doesn't have
the Versioned extension in this example, it would not work for class B.

Fixed this by extending augmentSQL on the actual data class and not
on the base class.
FIX 7742 Decode the URI encoded attribute before displaying it as the value for the tree dropdown
FIXED: Issue where urls with querystring arguments would not be properly concatenated with additional query parameters during ajax requests. The behaviour would not normally be noted except when using a module (such as Translatable) that adds parameters to data-url fields in forms.
FIXED: Issue where viewing an archived version of a page caused invalid SQL to be generated. This would only occur with subclasses of Page.
FIXED: Issue where versioned would join _versions tables on ID,Version instead of RecordID,Version

Updated translations; i18n for fieldLabels
BUG More robust url comparison in CMS

Avoid ajax reloads when URLs differ in irrelevant ways,
e.g. admin/?locale=de vs. admin?locale=de.
This caused problems with the translatable module
reloading page content where it didn't need to,
because some previous robustness patches to the same problem
didn't apply (they only removed trailing slashes, ignoring
query parameter strings). The visible problem for this was
a broken tree panel, because it was ajax-loaded in parallel
with its container. Depending on ajax response order,
this would break the inner panel (in this case the tree),
since its original container was replaced with a new DOM.
ENHANCEMENT: Ntfcatn. image embedding(trac #7438)

Adding an additional warning / notification message, when author embedds an external image.
Fix TreeDropdownField toggle alignment in FF

See pull request #598
API Allow to force URL reload, while replacing the history state

Comes with a wrapper for easy reloading of the current panel.
API Debug::showError() no longer calls exit() (fixes #2644)

Remove exit() from showError to continue execution after an user_error of warning (warningHandler) or notice (noticeHandler) level.
