Minor Update - Sigma 6.1

Added: [list] [*] A better Weapon Wheel, you can choose the weapon by simply flicking the mouse rather than manually pressings a button [*] Fixed a weapon wheel bug where it wouldnt work on certain areas [*] Improved the default none-Shocker punch [*] Added a button to reset the portal facility upon completion, for Leaderboard nerds [*] Fixed multiple typos, corrected "Score" in the Leaderboard to "Time" [*] Improved Wall jump velocity roll-off slightly [*] Several other small bug fixes [/list] Let me know of any other changes I should be making! Hopefully I'll try to add them either in a small patch or the next major update.
