Added autosave (and added an Other section to Options)

[Mode8fx]

Added an "Other" section to the Options menu, and added an Autosave feature to this section. The possible options are:

Off

• No effect

Mid-Level Only

• Skips mid-level dialog box when you get a star (like "Wow! Another power star!" or "You got 8 red coins [in a Bowser level]!") and saves the game immediately after the star animation.

End of Level Only

• Getting a star that kicks you out of the level skips the coin tally, animation of Mario taking his hat off, Save screen, etc. In other words, the game saves and you can start moving as soon as you exit the level.

On

• Combines the previous two options into one.

I just fixed the conflicts, so it's ready to be merged now. Always remember to sync your fork with the repo to make sure you're not working off an outdated build!
