Ability to import preferences from other terminal emulators

[waldyrious]

Is your feature request related to a problem? Please describe. As a user of GNOME Terminal who just started experimenting with Terminator, I would like to have a way to import all the compatible preferences (cursor shape, font family and size, colors, etc.) without having to recreate them manually in Terminator.

Describe the solution you'd like A feature to import preferences from supported emulators (even if just GNOME Terminal) would be great for adoption and providing more streamlined first experience for Terminator.
