Primary change is to replace most control/window borders with
AUI pane borders. We implement our own AUI border drawing
routine which avoids the ugly one-pixel white frames around

Also increases the signal-to-noise ratio of all the pane
creation code in the various frames.
This removes the existing constructors so that all parsing must
be explicit and callers are made aware that they need to think
about illegal characters, malformed ids, etc.
