Use -map option in ffmpeg process

Using " -map 0:v -map 0:a " to map all video and audio streams from the input to the output. This is much simpler than looping over -newaudio and -newvideo options.
remove ffprobe of av track counts

Remove ffprobe's count of av tracks (not necessary with use of -map option)
Use -vsync passthrough in ffv1 process

Being explicit to preserve each frame's timestamp. This may help with some QuickTime files.
make parse ffmpeg version more flexible

Added --ignore-case since "FFmpeg version" is lowercase in modern versions. Note that scraping this line doesn't inform to much. Consider using the output of `ffprobe 2>/dev/null -show_versions -of json`.
Update src/transcoder/share/mysql

In ffv1 encode use gop_size=1. ffv1 (by current default) use a >1 size gop and reuse arithmetic coding state from one frame to another. Declaring -g 1 will add a small percent to resulting filesize by include error resilience by limit bit errors to affect data per frame rather than per gop.
Ensure h264/MP4 files for access use yuv420p.

More modern builds of libx264 incorporate support for many more pixel formats. FFmpeg's default handling if to preserve pixel format through encoding if feasible. In this case the intent is transcode for accessibility, thus changing to yuv420p pixel format.
Remove unused -ac in the ffmpeg mp3 process

This ffmpeg command had two uses of -ac. The first would be ignored anyhow so I removed it. Also -ac is used to imply channel count, but the ignored -ac part here counted audio tracks and not channels. If the first -ac was used then single-track stereo audio files would have been converted to mono mp3s (so glad it was ignored).
Remove -ac from wav encode, use ffmpeg's default.

The ffmpeg wav encoding uses the audio track count as the channel count for the single track output [audio_channel_count!=audio_track_count]. I removed this -ac option so the output will still be single track but the channel configuration will be based on ffmpeg's evaluation (and not input track count which would almost always be 1 and thus force mono output).
Added colour to git update without rebase.
Changed AtoM installation so it pulls from public Git repo.
Changed svn up to git pull for AtoM in dev-helper.
Changed directory references from "qubit-svn" to "qubit-git".
Removing access conversion of .jp2 files.

note: also identified jp2 as valid access format.
Initial set up to handle bulk-transfered items in CONTENTdm DIPs.
Allowed for 0 dmdSecs in CONTENTdm DIP creation.
Cleaned up logic around handling 0 or 1 node in dmdSecs.
Update .gitignore with bytecode python files
Continuation of changes to handle bulk-transfered items in CONTENTdm DIPs.
Merge branch 'master' into contentdmbulk
Added .pyo and .pyc files to .gitignore.
