Now the eyes go to a khaki color and "< < < LOADING < < <" displays
during the skill startup. When Padatious finishes the first training
we now emit a "mycroft.ready" on the messagebus.
A change to the skill_mark_1 to look for "mycroft.ready" instead of
"mycroft.skills.initialized" provides a good visual change to show that
it is ready for use.
