Add a possibility to show a progress dialog on dialog sample startup.

Add a command line option to the dialogs sample to allow testing of different
wxProgressDialog styles more easily. This also tests for showing them before
the main event loop is started (see r65499).

 This sample shows how to use the common dialogs available from wxWidgets. These
 dialogs are described in detail in the @ref overview_cmndlg.
 
+In addition to the dialogs accessible from the sample menus, you can also run
+it with a <code>--progress=style</code> command line option to show a
+wxProgressDialog with the given style (try 0 for the default style) on program
+startup, before the main window is shown.
