Added support for name prefix and multiple global files.
Name prefix is useful on iOS since multiple domains are not supported (each loaded swf can have a different name prefix to avoid symbol name conflicts).
Multiple global files allows you to specify air or player global SWC plus any other RSL SWCs you want to prevent name obfuscation.
Disabled sealed text since it may cause a security issue with flash player. (due to an unreferenced symbol?)
