EN/FF: Various changes to the Microphone class

[mdcutone]

Some fixes and changes as listed here:

• Removed volume setting from Microphone class. Doesn't work anyways but didn't raise errors originally.
• Added audio latency mode. Default value comes from prefs but the user can specify a value to override.
• Added logging to various events during the creation and use of the class.
• Some doc changes.

In the warning:
Text-to-speech recognition module not available it might be good to give the name of the python package that needs to be installed, or tell them to pip install SpeechRecognition

[isolver]

the coder\input\latencyFromTone.py demo no longer runs.

Traceback (most recent call last):
  File "D:/DEV/my-code/psychopy/psychopy/demos/coder/input/latencyFromTone.py", line 38, in <module>
    names, idx = sound.backend.get_input_devices()
AttributeError: module 'psychopy.sound.backend_ptb' has no attribute 'get_input_devices'

Not sure if this dmeo should be fixed or changed to be a demo / test of the new recording functionality.

[isolver]

Update: Using Audacity I can record audio at normal volume fine, so it seems that the latest mic update records with very low input levels. Maybe the volume code was doing something?

[TEParsons]

Mine is a little quiet too - quieter than when recording from current dev branch

[mdcutone]

Makes no sense why this would be happening. The volume code wasn't there before and it worked fine.

[mdcutone]

Okay seemed to be a problem with the WASAPI driver not working well with audio latency classes other than zero.
