Headless support?

[C-Duv]

Running the script on a server without a display fails with:

_tkinter.TclError: no display name and no $DISPLAY environment variable

Streamer Username to record: foo_channel

Traceback (most recent call last):

    self.tk = _tkinter.create(screenName, baseName, className, interactive, wantobjects, useTk, sync, use)
_tkinter.TclError: no display name and no $DISPLAY environment variable

Forcing a dummy value with export DISPLAY=':0' also fails:

_tkinter.TclError: couldn't connect to display ":0"

Is the script (and the underlying streamlink library) able to work without a display?
