new getControlLines() and getSupportedControLines() methods

Browse Source 
getControlLines() requires less USB calls than calling getRTS() + ... + getRI() individually.
getSupportedControlLines() tells you, which control lines are supported by a driver. Previously you had to check the driver implementation.
