Adding New Semiconductor Patterns

In the manufacturer handler's initializePatterns():

registry.addPattern(ComponentType.MOSFET, "^NEWMOS[0-9].*");
registry.addPattern(ComponentType.MOSFET_MANUFACTURER, "^NEWMOS[0-9].*");

Add to getSupportedTypes():

types.add(ComponentType.MOSFET);
types.add(ComponentType.MOSFET_MANUFACTURER);
