[Feature] Ability to Launch KSP from consoleui

[VoreckLukas]

Problem

I'm running linux and the gui on linux honestly looks horrible, so instead im using the consoleui. but one thing I noticed was missing Is the "Launch KSP" button the gui has. SO I have topen steam seperately and launch ksp through steam

Suggestions

Just add the option to launch KSP from the consoleui. Best way would probably to add it in the menu above game instance settings
