513 persist application layout across restarts (#514)

* Stores minimal main application window location and size/layout settings
to allow application to be restored to the same size/location on
restart.

* Adds column width monitor to all tables in application that stores the
column width settings in the user preferences so that on restarting
the application the table column widths are restored to the previous
widths.
