Bug Fix and Sparkfun RedBot Examples Merge

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

Control-C handling removed from library.

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

Python3.5 asyc/await support + WiFly support for SparkFun RedBot

This release requires Python 3.5 or greater. If you wish to use Python 3.4.3, then please download version 1.9.

This release implements the new async/await syntax. In addition, support to control a SparkFun RedBot robot with a WiFly module were added.

Applications developed with release 1.9 should still continue to function with this release.

Sparkfun RedBot Specific Changes

1. Modified FirmataPlusRB to detect encoder changes on rising edges only. Previously was both rising and falling.
2. Parameters for encoder_config in pymata3 were made consistent with pymata_core.

Bug Fix Release for PyMata3

Modified all calls to pymata_core from pymata3 to use loop.run_until_complete().
Default value for the duration parameter in play_tone (pymata3) is set to None.

Hall effect wheel encoder data reporting format modified

This release was created in preparation for the upcoming release of a Sparkfun RedBot support library .

In addition, an additional version of FirmataPlus has been added. FirmataPlusRB provides support for the RedBot.

Resolutions for issues #11 and #12, some minor bug fixes and code cleanup

This release resolves some open issues and fixes some minor non-reported bugs.

2nd Take on fixing OS X auto port detection

This release searches for possible OS X ports connected to an Arduino.
Also, minor code cleanup.

Bug fix and enhancements

See changelog.md in the documentation directory for details.

Address Issue #4

i2c read request reply modified so that data format is expected format and not firmata 2byte format
