Bug fix 1.3: secret grandpa edition

Just a few fixes.

Changelog:

- Fixed secret Gramps. You could clip the camera through the wall at the end of the game and see a Gramps that wasn't supposed to be there. Oops! (Thanks to Zagonite on youtube for finding this!)
I almost debated leaving this in as an accidental easter egg, but it just felt too sloppy so I fixed it.

- Fixed the credits not being able to be sped up on gamepad. By the way, you can speed up the credits by holding the OK button. This was a dev tool that I decided to leave in because why not?

- Added a loading indicator. I noticed the intial loading of the island could take a potentially concerning amount of time, so I added an indicator that says when the game is loading. No one complained about this, but it bothered me and it was a simple addition.

- Actually remembered to update the version number on the title screen.

With love, Cortok
