WindowCommands.ShowSeparators=False is ignored

[MrMitch]

When adding a set of commands to the MetroWindow, the separator are always visible even with the ShowSeparators attribute set to false.

I have created a basic project demonstrating this here : https://github.com/MrMitch/MahAppsSeparatorsError

Tested with version MahApps.Metro.1.1.3-ALPHA217
