* 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

In the example, if you have an enum of Enum("Something,Don\t know") in your `DataObject::$db` array, then dev/build will *always* say this field has changed, because `MySQLDatabase::showFields()` returns the escaped string specification of the field with instead of \.
This converts the field spec so that is escaped to \ correctly so the change detection in `Database` is correct.
- Changed application order
- Fixed layout trigger after preview toggle
- Replaced button row dimension approximation with double application of jQuery.layout() - once before sizing the action panel height to set correct width on container, then again for the height
MySQLDatabase::enumValuesForField() - Added stripslashes because backslashes are escaped in the type description
DataObject::requireTable() - Added double quotes to column names in automatically generated indexes for many_many relationships
DataObject::write() - Escaped class name for DB query
DataQuery::getFinalisedQuery() - Escaped class names for DB query
MINOR Use injector for creating many many list objects
MINOR Use injector for creating objects from within the DataList
MINOR Use Injector::inst() for creating objects; cannot rely on this->injector being present due to many classes being created with 'new', so use inst() directly
MINOR Remove injector autoset property for now; automatically setting it breaks a few test cases that don't know about it for now, and it's not needed just yet
BUGFIX Versioned's constructor doesn't provide suitable defaults. Previously a bug/feature in singleton, where it would pass null,true as params to strong_create, which would then get passed through as params to Versioned's constructor, meant that the code still executed fine (as was set to something that wasn't an array, so the null and true were instead taken as args). The fact that the usage of singleton(Versioned) never really used the classes code, purely for value lookup, meant that this never propagated errors. I've now switched singleton() to use the injector for retrieving values, which means these dud values are no longer passed through
CHANGE Given that Config::inst is an implementation of the singleton pattern itself, I've removed the extra call to singleton(). A side effect of this is that it gets around a possibly nasty circular reference with the dependency injector (which relies on the config object); in future, this dependency structure should really be structured from the DI directly.
MINOR Change singleton and strong_create to use dependency injector
