-- removed aliases set_icons, icons, add_icon, add_icons for set_icon (which only applies to the dialog, not to controls, so there can only ever be one)
-- finally fixed (I think) peculiar concentric rectangles appearing when tootips specified for controls -- Previously, set_tooltip only worked if a tooltip had been specified when a control was defined. Now that's no longer required: you can create a tooltip on the fly. Also, set_tooltip takes optional <tooltip_style> and <font> arguments. And you can use the same service to kill off a control's tooltip. -- Added dialogPluginFunctions.txt to be used as a file menu, perhaps merged with pprofunctions.txt. -- There were errors in dialogPluginDemo.ini and dialogPluginDemo.txt, so the sample script dialogPluginDemoFromConfigFile.powerpro didn't work right
