Hotfix demo.1.2 & AVAST

**Note for AVAST anti-virus users: ** If you have trouble installing the demo, try checking the anti-virus log and manually adding Regiments.exe into the exclusion list. Avast seems to mark Regiments.exe as an "IDP.generic" threat due to the built-in automatic crash reporter.

Along with bug fixes, this update adds several requested features:

• Added hotkeys to hide UI & Cursor - check Controls settings

• Added ability to invert Camera Y Axis rotation

• Fixed SAM-vs-planes engagements: missiles can now properly apply suppression and damage to the planes.

• Adjusted objective zone visuals for better clarity, both on the main map and the minimap.

• Bugfixes for several script errors
