Welcome: Start some performance improvements

This is essentially a widgets based re-implementation
of the current design. It is still using the QAIM based
interface layer between to the real data and display even
though this is not needed with this approach.
Removal of this layer would further reduce code size
and cycle counts.

For now:
               old          new
Load time    215ms        182ms
delete        22ms          2ms
