Pymata

When a command to reset the Firmata was received, the response tables were not rebuilt correctly after clearing.

- Merged latest changes for SparkFun RedBot experiments
- Fixed bug in accepting com_port parameter
- pymata_iot sends reset to Arduino upon exit

This release adds an additional optional parameter to suppress status messages.

pymata.py:
**init**(self, port_id='/dev/ttyACM0', bluetooth=True, verbose=True)

Python 3.5 asyncio signal registering does not support Windows and only linux, so it was removed from the library. Applications will be responsible for control-c handling. There are examples provided here: https://github.com/MrYsLab/pymata-aio/tree/master/examples/control_C_handlers

There is no functional difference between this release and v2.03. Needed to bump release to keep PyPi in sync.

To allow a callback routines to re-arm latches and to make other PyMata calls, the thread lock was changed to an RLock.
