Allows for quickslots to be cycled using a new UI element

Left and right arrow cycle through quick slot sets.
Having the L button active (yellow underline) will load as soon as you change set.
Having it unselected, just changes the number.
Hitting S, will save your current quick slot layout, to the currently selected numbered set for later loading.
This can be closed using the X, or minimised using the arrow on the title bar.
You can re-open it using your Quick slot Token (everyone gets one now - upon being granted it, it saves your current quick slots to set 1)
