Version 3.0.6 - very minor changes

Just a very minor update to fix a few things I've found over the last few weeks.

Version 3.0.6:

• Fixed screenshake option not working at all.
• Fixed cutscene gallery being always unlocked. -- (should only unlock after beating the game)
• Fixed broken bandcamp link.
• Added links to Twitter and YouTube.
• Coffee price halved to 500.
