Fixes:
* Hacked in a fix to `ut.Pref` to prevent certain params from being dynamically
defined. Ultimately the structure of this class is poorly designed, so I dont
feel bad about hacking it like this.

* Fixed issue in color text where some colors that were used are no longer
supported. Hacked around by changing them to a supported color when an
exception is thrown.
