changed slider issue, fixed monitor bug, added basalt.isKeyDown(keys)

Slider: added setIndex() and changed setValue behaviour
Monitor: Changed monitor draw priority so input's cursor still shows (have to figure out why its even hiding)
added new function where you can check if a user is holding a key currently down
