audio-netsender: Fix sample rate validation
* audio-netsender: Fix sample rate validation
This change makes a simple change that makes the function compare the requested sample rate against the valid rates instead of the indices of the valid rates.

A wav encoder will be useful for returning easily playable audio files to users of vidgrind that are not familiar with PCM audio. Currently the encoder only support PCM data, but can be updated with other types. The encoder implements the writer interface.
* codec/wav: Add unit tests for wav encoder
Merged in create-wav-encoder (pull request #529)

(b *Broadcast) UnmarshalJSON no longer starts revid (see PR #510).
(m *BroadcastManager) MarshalJSON no longer needs to worry about slate exit signals due to broadcast status (see PR #511).
Merged in 421-fix-JSON-marshalling (pull request #528)

This is done so that a SCUHU users can see the pi IP address has connected to their hotspot without having to then log in via SSH to turn the wifi off before deployment.

We need to actually get the returned value from
initOrStartPipeline and set the pipeline.
* vidforward: add some logging to config load
* vidforward: update utils version

The reader and writer pipes should be created on call to Start
and not in NewManualInput. This is so that if Close is called,
which will close the reader and the writer, a call to start will
create them again.

vidforward: initOrStartPipeline
This function checks whether a revid pipeline has been created,
and if not creates it. It then also checks to see if it has been
started, and if not, starts the pipeline.
Using a env var in CircleCI, these tests will be skipped when commits are pushed to bitbucket.
NOTE: this is a temporary patch, and these tests should be properly reviewed.

This file used to be used for startup, but now we just start the
process directly in the service. It probably existed in the dir
last time this was tested so no errors were thrown, but on a clean
install this was a problem.
It simplifies things if getPipeline handles creation and starting
of the revid pipeline. We don't need to be doing this in multiple
places.

When saving and loading manager state to and from file, we don't
need to worry about the slate exit signals. Now that we have
broadcast status i.e. "play" or "slate", we can derive whether we
need an exit signal based only on that.

Config.RTMPURL was being appended when updated, which means that
it would just continue to grow, and by the time we actually try
to use the RTMP URLs that are stored, we end up using old ones.
Instead this should just be completely replaced.
The globalLogger type wraps a logger.Logger. If you use GetLogger
which gets the global logger (which provides an interface
logger.Logger) a type assertion to JSONLogger will fail, because
the type is actually globalLogger. We need to provide the
underlying logger instead when we return from GetLogger.
This change improves the mechanism that deals with recv requests
from non active macs. We're no only logging every minute so that
we don't clutter the logs. We're also dealing with both non active
and slate recvs with the same mechanism using a switch.
For control requests, we only update aspects of the broadcast if
they have changed. Therefore, if the urls list has not changed
the revid pipeline is not updated, similarly if the status has
not changed, we don't do anything there.
This change adds a file watcher and then uses this file watcher
to perform updates based on changes in a configuration file. This
configuration file contains logging parameters for the time being
in the hope that it will help with debugging.
Testing was also added for this functionality.
