Finished implementing alphabetical sort.
Along the way, I gained new
appreciation for the OpenGL canvas system I implemented for Revision
Graph, for it is vastly superior to this QCanvas crud in many ways.
Might go ahead and implement this in Revision Graph just to marvel at
how many fewer lines of new code it takes.
Turn on alphabetical sort by adding the "-n" option to the command
line ("-n" for "name sort"). This feature is not accessible from the
settings dialog, nor does it persist after a refresh, but it DOES stack
with "-o outputfile", which as far as I know is all that anyone needs.
