Reduce flashing redraw from automatic partition selection (#696149)

Automatic selection of the largest unallocated partition caused flashing
redraw of the partition graphic and partition list.  Both the partition
graphic and partition list were being drawn blank then redrawn fully
populated.  This only happened on some distributions including:
CentOS 5.10, 6.5, 7.0, Debian 6, Fedora 14, 20, Xubuntu 14.04 LTS.  Did
not happen on: Kubuntu 12.04 LTS.

This is a workaround, not a complete fix.  It moves automatic selection
of the largest unallocated partition to after processing of the GTK
Event loop in Refresh_Visual() which redraws the partition graphic and
partition list.  These visuals are now drawn only once, fully populated,
however this draws them without the selected partition.  The partition
selection is then drawn afterwards which causes the selection to flash
instead.  This is significant improvement to the whole partition graphic
and partition list flashing when redrawn.

Bug #696149 - Double refresh of display introduced with default
              unallocated space
