Improved diag. logging on renderer startup.

[ohlidalp]

To help diagnose #3141, I added extra logging of renderer config and startup.

• Displaying the fatal error dialog will now be logged to RoR.log - see file ErrorUtils.cpp.
• New entries in RoR.log - see file AppContext.cpp, function SetUpRendering()

@CuriousMike56 you most commonly support people with startup problems - do you find this useful to merge, even if we can't resolve #3141 ( which seems to be related to dual monitors in mirror mode )

@ohlidalp Extra logging is always helpful, this is good to merge.
