Added paranoia about making sure ergoemacs-keys are turned on
appropriately if something in the shortcuts messes up the variable state.
Bugfix for looking up ergoemacs-defined modes-specific commands.  For
example when defining C-b to bold region in org-mode, M-n in colemak
also bolded the region...
Added C-b for bold C-i for italic and C-u for underline...  But maybe
I should rethink the underline gig.
Decided to remove C-u.
