Version 1.5.6 (bugfix)

changes:

• fix serial port list, see note (#93, b7158de)

Version 1.5.5 introduced better serial port descriptions by querying the Windows Management Interface for a list of ports, instead of using SerialPort.GetPortNames(). This worked fine with my hardware, but some Arduino boards would not be listed this way (reported by @sheenygami and @deHarro, thanks guys!). This bugfix combines the output of both methods, so these boards are listed as 'COMXX', just like before.
