Tutorial Refinement and UI Readability

Howdy Frisbros,

Just releasing a new build with some of the final bug fixes before launch!  This time I focused on improving the tutorial for the game to make it more comprehensible (Taking inspiration from the quote: "If I had more time, I would have written a shorter letter.") and also some UI fixes to make it easier for players to know what hole they're one.  Finally I added a single extra respawn point in one of the levels, not because it was broken but the disc just respawned far enough that it go annoying.  Anyway, TWO more days before release! Can't wait.  Cheers!
