Added support for embedded ROM images in simulators.

Browse Source 
This allows a single simulator executable to be a completely useful component (for those simulators which dynamically load ROM or other boot code).
Meanwhile, we continues to allow the explicit use of a user's preferred ROM or other boot code as well.
A build option is provided in the makefile to not build with the included ROM functionality if desired.
