[Feature request] Double click demo file to play it

[temx]

Assuming this is from the OS shell, you can set your .dem handler to launch vkQuake with the appropriate parameters. For example in Windows you can use a cmd file like

for %%F in ("%~1\..") do set modname="%%~nxF"
cd /D "%~dp0"
vkQuake -game %modname% +playdemo "%~nx1"

place it along vkQuake and assign .dem files to it (or just drop them on top of it).

I do like the feature some Doom source ports have where they do the right thing when you directly pass a file as a parameter. Quake could interpret directories as mods, map files as game + map, and dem files as game + playdemo requests.
