Use consistent nomenclature for commands

**Problem/Use Case**

Right now, commands that export or save files don't use a common convention for naming.  It would be ideal if we could change them to use a consistent prefix.

**Proposed Solution**

Have all output commands start with `save-`:

 - `save-html`
 - `save-csv`
 - `save-qp`
 - `save-images`
 - `save-videos`
