GUI Always Start Headless

[jeremywj]

I would appreciate an option in the GUI to always start a VM in headless mode (without holding down shift key which I forget to do about 99% of the time).

Thanks.

This is long implemented, just not available in the GUI, because we have no good idea how to integrate it in a way which won't confuse more users than its audience.

VBoxManage modifyvm "vmname" --defaultfrontend headless

Documented as the last option in section ​8.8.1. General settings.

Would be great if we have the defaultfrontend option on GUI. May be a good place to put this will be vmname -> settings -> Display -> Default Frontend (GUI, Headless, SDL, Separate)
