Updated to Boaty McBoatface Island Adventure 0.1.2

Patch notes:

• Updated the sound engine, FMOD by Firelight Technologies Pty Ltd to version 1.10.0 - added a logo for them in the splash screen/pause menu.
• More sound effects added.
• On player feedback  - The boat cannon can now hold charge. You can keep the cannon at max charge now and release it when you want (and not immediately when at maximum charge) - this should make it easier to do 'drive by' shots now.
