This change is the first of a few areas to unify the selection
and multi-action logic of lists in TYPO3 Backend.

This change moves the checkbox to the very beginning
of each row within the File Browser popup
(e.g. Select a File in Pages > Media of Form Engine)

In addition to the "toggle selection" button, there is now
a "select all" and "select none" button.

When an item is selected, the whole
item is now marked as selected.

This code now uses the TYPO3 icons instead
of the Font Awesome icons.
