[Bug Fixes] 6AM Version 1.1

Screen Resolution/UI Bug
There was an issue with the screen resolution that caused UI elements to appear misaligned at certain resolutions. This was due to the default native resolution being set when starting the game. This has now been changed to a default of 1920x1080. 

Audio Bug
There was a bug that caused an audio trigger to repeat whenever the player entered that specific area. This was due to a missing boolean value that tracks if the audio has already been triggered - without it, the audio trigger was being played each time. This has now been fixed and should only play once (as intended!).

Optimisations
Lightmapping optimisations and improvements to occlusion culling.
