1.2 Slider Update

Prefab was updated this morning with some minor changes:

-A bug that caused options to reappear when the menu was closed has been fixed.

-Higher default option count. Raised from 4 to 6.

-Code has refactored comments to hopefully make it easier to add or remove options. 

-Original "No Slider" version has been re-listed if you don't want the slider functions.

-- A new bug has been found that causes some issues when moving the slider too quickly. Working to find a fix.
