new BlockUofS button

Ive had a go at skinning the button (based on the stuff i stole from your skins)

we will need to be able to pass variable from host component -> skin and have skin do things because we want the button to stay 'selected' for as long as the Unit of sound is highlighted in the block words. but we only want the (( )) when we are playing a clip. i would imagine defining a bool "playing" on the button component and then using this variable from the skin to show / hide the (( )) parens.
