Run Space Engineers with Plugin Loader on Linux - New Method

Adapted from @GangolfOvaert's comment.

1. Download the latest Space Engineers Launcher into the Bin64 folder of the game
2. Set Space Engineers launch options in Steam to bash -c 'exec "${@/%SpaceEngineers.exe/SpaceEngineersLauncher.exe}"' -- %command% (arguments can be added after %command%)
3. Launch Space Engineers from Steam

This method does not use SpaceEngineersLauncher.py, so downloading it is not required.
