In our quest to remove PluggableTextMorph :)

Hi

as you saw we mainly Frank helped by Alain started a fight against
PluggableTextMorph and started to replace
PluggableTextMorph with Rub equivalent. It will help us also to migrate
to Bloc.

We have rewriten Workspace, TestRunner is on its way.
So we will replace soon the old Workspace with a new ones (with most
features kept - we just did not keep the broken ones).

Stef and Franck
