Adds two menu toggles
Toggle web security
Toggle SharedArrayBuffer
This will allow the user to easily enable or disable PSP & Dos box emulation w/o needing to modify any code.
After toggling either web security or sharedarraybuffr you will need to press the restart now button for the settings to actually apply.
Settings are stored to settings.json file for future loads.
