From 6e9ff495eb082aeb49e6a1da23a7827d3fcd0fde Mon Sep 17 00:00:00 2001

Subject: Add parser error handler.

OpenCOLLADA is a validating parser, so is pretty strict about document form. The added error handler will print out any errors the parser finds. A pop-up will be shown too, advising the user to check the console for the error log.
