* ENH Make all GridField components injectable.
Some components were already injectable, but all GridField components shipped in silverstripe should be injectable.
This makes it a LOT easier to make global project-specific changes to a given component.
The new AbstractGridFieldComponent also makes it easy to make similar wide-spread changes in the future.
* DOCS Encourage injection for GridField and GridFieldComponents.
* ENH Reduce duplication of code in GridField view and edit buttons.
* Fix syntax error
