Mr Eaten's Open Skies v1.0.1 Monarch compatibility test 3

Third Monarch compatibility test prerelease.

Installer changes since test 2:

• Replaced fragile batch-file installer logic with a PowerShell installer launched by install.bat.
• Supports pasted or dragged game paths with spaces and parentheses, including Program Files (x86), with or without quotes.
• Still writes install-log.txt next to install.bat.

Use option 2 for Monarch/Furthest Frontiers installs.
