resolves #88 update quick ref with 0-1-4 changes

- link to icon info in user manual
- inter-doc references
- video macro
- code block with non-select callouts
- code block with xml callout
- pygments
- checklist
- list marker styles
- list number styles
- implicit table header row
- options shorthand
- role and anchor inline shorthand
- image formatting
- toc syntax
- include content form URI
- role for backticked text
- section with link to user manual and help

I think this captures the 0.1.4 syntax and attributes that apply to the quick reference guide.
In some places I just mentioned that additional attributes, styles, or options were available and linked to the appropriate section in the User manual.
Now, I think it is time to spin off separate issues for editing and refining the quick reference guide per different topics (i.e. a very simple syntax quick ref, an attribute quick ref, etc.)
