(svn r3740) -Feature: [OSX] added OS version, CPU type and newGRF settings to assert window and a message to tell people to add that to a bug report

It also adds a new error window, which can be used just like assert, but it is also active when asserts are turned off
	This is useful for places where it's really important to check even if assert is turned off. It's not used in the code yet
