KeyboardSettings: Add checkbox to enable Caps Lock mapping to Ctrl

Browse source 
This patch adds an additional control to KeyboardSettings allowing
the user to map Caps Lock to Ctrl. Previously, this was only possible
by writing to /sys/kernel/variables/caps_lock_to_ctrl.

Writing to /sys/kernel/variables/caps_lock_to_ctrl requires root
privileges, but KeyboardSettings will not attempt to elevate
the privilege of the user if they are not root. Instead, the
checkbox is rendered as un-editable.
