Title: DOC : edits to optional dependencies

- cleaned up failed merge
- added external movie programs to docs (closes #2490)
- added all the external libraries that are include in the source
tree
- added six as explicit dependency. This was discussed before and
rejected, but I added it here because we now have a minimum version
check which should be documented.
