Introduce new LeftAndMain_HTTPResponse class for this purpose,
to mark a response as finished regardless of HTTP status.
This is required for ajax responses which do redirects on app layer
rather than HTTP (to avoid double processing).
Specifically required to decorate LeftAndMain->init()
in the 'translatable' module (TranslatableCMSMainExtension),
which marks the response as finished through its redirect,
avoiding further processing after init().
As ModelAdmin puts classes directly into links, a namespaced class
has its \s turned into /s, breaking the links. This escapes them by
converting each \ to a -, then converting them back when loading.
Nasty issue where nested requests to sub-controllers within LeftAndMain->EditForm() would fail because of
LeftAndMain->currentPageID() being taken from the URL, even though it was a field action name.
Example: POST /admin/pages/edit/EditForm/field/MyGridField/item/1/ItemEditForm/field/MyUploadField/upload
The current ID would be detected as "field" in this case.
Bug was previously fixed for AssetAdmin.
7427 was mostly fixed by Ingos previous patch. But two batch actions, delete from draft site and delete from published site werent returning
status messages. Abstracted out the status preperation code that the batch actions that were returning status messages were using, and
used that to add status messages to the problem two
---
* Added a separate component to grid field to hold buttons.
* Updated templates for changes
* Updated comments
Conflicts:
css/AssetUploadField.css
css/GridField.css
* Alter Grid Field "Add New" Button to take the name of the table (i.e.
"Add Member")
* Alter table names in security section to be singular so the button
text makes sense
Form actions assume that they are reloading the form afterwards. But
this is not always the case - for example "delete" action will redirect
back to the panel, so we need to be able to set the X-Pjax headers
accordingly.

These are some enhancements + tweaks I made as part of getting the advanced workflow module running in SS3:
* Added a readonly view button and action to GridField.
* Made LeftAndMain::getResponseNegotiator() public so CMS extensions can use it to generate responses.
* Fixed top tab background, made text more readable (http://i.imgur.com/yDmmY.png).
* Allow fields in the CMS to not be change tracked using ".no-change-track".
* Made all icons 16x16 (some were different sizes, being cut off), and allow them without .ui-state-default.
* Fixed ToggleCompositeField and tweaked field styling.
