Can't mirror to all external displays

[jross-nu]

I'm getting the following error when executing display_manager.py mirror enable main all

Traceback (most recent call last):
File "/usr/local/bin/display_manager.py", line 1257, in
main()
File "/usr/local/bin/display_manager.py", line 1250, in main
commands.run()
File "/usr/local/bin/display_manager.py", line 682, in run
currentMirror = display.mirrorSource
AttributeError: 'list' object has no attribute 'mirrorSource'

I can mirror to individual external displays.

@jross-nu Thanks for the feedback, we will add it to our todo's and get to it when we have the bandwidth.
