Style variable names

Browse Source 
This adds style support for variable names.  For the time being, this
is only done in backtraces, not in ptype or print; those places do not
use ui-out and so would need ad hoc changes.

This also adds styling to the names printed for local variables in
"backtrace full".  This code does not use ui-out, so the styling is
done using the low-level API.
