Space delimiter is often confused by browsers, and encoded as %20 which
breaks the shortcode system. Change to comma delimitation has already
been implemented, this is a followup cleanup.

We removed this because it depended on GeoIP, which was weird, and had its own dependancies.
But Zend_Locale is included in core, and can give us all the data we need for CountryDropdownField
When adding media via the HtmlEditorField dialog, the value of the URL field wasnt being validated. Youd get different errors depending on if the field was empty
or if it had text, but it didnt look like an absolute URL to HtmlEditorField#viewfile.
This adds some javascript validation to make the text field look like a URL field
Only use relField() when it exists (usually on DataObject),
otherwise fall back to method or value returns
(same as original GridFieldDataColumns behaviour).
HTML in tree nodes is already used to render page icons via SiteTree->TreeTitle.
In order to select the initial value correctly via HTML5 data attributes,
we need to encode any HTML values.
ImageFormAction is deprecated, using the new API results in a submit input rather than an image input being generated. Added hasAttribute helper to FormField as well as test coverage.
* Use jquery ui accordion for the field, and implemented an admin theme.
* Made the setting of configuration consistent with other form fields.
* ToggleComposteField->startClosed() has been deprecated in favour of
setStartClosed().
* Removed public access to the heading level, instead use getHeadingLevel()
or setHeadingLevel().
* Add arrows back to edit-all toggle button
* Don't show dimensions if the item being inserted doesn't have them.
* Set pop-up windows to be a percentage of the window height for better
use of space
* Fix broken fieldholdersmall styling within files edit
* Add placeholder if no preview
*Take out minFileSize so upload will work on Android phones
API CHANGE: Added GridField::getDataFieldValue() to encapsulate field lookup for all components.
API CHANGE: Allow 'callback' key to be specified in a GridFieldDataColumn column info. In this case, title should be put as the 'title' key of a map rather than simply the column info.
