System variables -> nashorn parameters

For debuggabilty this patch would help a lot:

I.e. setting an environment variable like -Dnashorn.args="--lazy-compilation --log=codegen" would pass the corresponding flags to Nashorn. This would help me both with node debugging and the current JavaFX debugging. If this has no security implications - please tell me if it does, can we go ahead and push this?
