Files cannot be moved from one folder to another without using the mouse

[Jono Mingard]

In the file browser (eg. on /artefact/file/index.php) files can be dragged into folders, but there is currently no way to move them using the keyboard. This is undesirable for people who prefer to use the keyboard and critical for screen reader users who rely solely on the keyboard for navigation.

It would be nice if activating the icon (by pressing Space or Enter) brought up a list of folders it can be moved into like in http://devfiles.myopera.com/articles/735/example.html - the icon alt text could then be changed to something like "File: Press space to move to a folder"
Alternatively checkboxes could be provided for selection.

Make file browser keyboard-accessible (Bug #1262904)

Adds tabindex to file icons so they can receive keyboard focus. Pressing Space
while an icon is focused brings up a menu where the folder to move to
can be selected.

Also adds "Folder:" text to folders in the file browser and adds accessible text
to parent folder links.
