Redo openpage in GettingStartedPanel to use BowlerDocumentationFactory
Merge branch 'GUI_Dev' of https://github.com/NeuronRobotics/NrConsole.git into GUI_Dev
Created NRConsoleDocumentationFactory.
Updated all calls to open documentation in browser window to use NRC or
Bowler Documentation Factories.
Did some minor clean up of altered files (removed unused or commented
out code, did some minor formatting, corrected some comments).
