Bugfix: user-provided paths may now contain spaces

Previously, paths containing spaces would be interpreted by python's argument
parser as multiple separate arguments, causing it to fail. Now we escape paths
inside PythonWrapper using std::quoted().

* Improve PII filtering. Python output would contain multiple path separators
  (like C:\\Users\\foo\\), defeating the PII regex.
* Silence compiler warning in PII filter.
* Document usability improvements.
* Transcription layer exponential backoff goes to ~infinity when paused.
  This is a hack, since we really don't need to transcribe at all when paused,
  but it lets us keep the code simple. Good enough until the next rewrite.
* Shader only samples background when necessary.
* Limit matchStrings() print()s to DEBUG mode
