Minor updates

Progress has stalled since I started working full-time end of last year. Rest assured my projects have not been abandoned, just delayed.

Finally some small changes after a long period of absence:

• Additional graphics in the title screen
• Added hotkeys to disable shadows and post processing which should hopefully help the game to run better on lower spec PCs (F1 toggles shadows, F2 toggles post effects)
• Camera has been pushed in for a more intimate viewpoint
• Resetting the camera now centers the camera on the back of the character
• Shoulder button configuration on the gamepad has changed (inspired by Resident Evil 2: Remake controls)
