Adding New IC Patterns

In the manufacturer handler's initializePatterns():

registry.addPattern(ComponentType.OPAMP, "^NEWOPA[0-9].*");
registry.addPattern(ComponentType.OPAMP_MANUFACTURER, "^NEWOPA[0-9].*");

Add to getSupportedTypes():

types.add(ComponentType.OPAMP);
types.add(ComponentType.OPAMP_MANUFACTURER);
