Title: Some CHEBGUI tidying.

* Use just one string for the 'Ultraspherical' button, so that
we don't get weird results when resizing font.

* Moving some initialization steps into the @chebguiController
class. Makes code easier to maintain via version control.

* Getting rid of a redundant 'envelope' button from the .fig file
that we were not using anymore.
