Tweaks: naming, whitespace, collapse all recipes

kfrn
4359d6dd4a Update 'show/hide recipes' (expand/collapse) functionality
Previously, it would expand the recipe if currently collapsed, and vice versa.
Now, if any recipes are currently expanded, it will collapse all; otherwise, all recipes will be expanded.

The 'expand all' functionality is necessary for full-text searching.

<p>Notes: You can choose which fields to write by repeating <code>-metadata field_name='Content'</code> for each desired field. Flags for commonly used fields (such as those recommended by the <a href="http://www.digitizationguidelines.gov/audio-visual/documents/Embed_Guideline_20120423.pdf">FADGI guidelines</a>) are as follows:</p>

<p>Example: <code>-metadata originator='US, UW Libraries'</code></p>
<p>Additionally, users should be aware that BWF metadata fields are limited by characters, with some such as OriginatorReference maxing out at 32. Specific information can be found in the <a href="https://tech.ebu.ch/docs/tech/tech3285.pdf">Broadcast Wave Format specification</a>.

<h5>Get individual checksums for all video/audio streams ("Streamhash")</h5>
<p><code>ffmpeg -i <em>input_file</em> -map 0 -f streamhash -hash md5 - -v quiet</code></p>
<p>The outcome is very similar to that of "-f hash", except you get one hash per-stream, instead of one (summary) hash. Another benefit is that you don't have to know which streams, or how many to expect in the source file. This is very handy for hashing mixed born-digital material.</p>
<p>This script will perform a fixity check on all audio and video streams in the file and return one hashcode for each one. This is useful for e.g. being able to change to container/codec format later on and validate it matches the original source.</p>
<p>The output is formatted for easily processing it further in any kind of programming/scripting language.</p>

<dt>-v quiet</dt><dd>(Optional) Disables FFmpeg's processing output. With this option it's easier to see the text output of the hashes.</dd>

<p>The output looks like this, for example (1 video, 2 audio streams):
