Compatibility with terminus >2.0.0

[twfahey1]

Just updated to terminus 2.0.0, was getting the error that this plugin isn't compatible, manually changing compatible version bypassed, and seems to be working fine. Just figured I'd throw it out there, since prior to updating to terminus 2.0, I wasn't able to properly authenticate for site mount.

Thank you for the feedback @twfahey1. I wasn't aware anybody was actually using this plugin. :) I will try and tag a new release soon so this can be installed via composer.
