MerlinDevice tries to load truststore of type "trustStorePassword"

In the MerlinDevice class, if the truststore is null, the truststore attempts to load with a Keystore type of "trustStorePassword" instead of "trustStoreType".

Line: truststore = load(null,trustStorePassword,provider,trustStorePassword);

This makes using a physical truststore (such as the windows cert store) impossible. A quick work around would be to extend the MerlinDevice class and override the load properties with the exact same code except with the fix to that line.
