feat (sparkvault): naming and organization

Described naming conventions and smart folder usage for organizing the Sparkvault.
Coming back to this @mutewinter and @robtarr - I now see all the 3 letter acronyms in Harvest.  I'm not a huge fan of them overall, but we can try it.  They're going to become vague very quickly IMO and they're really only known to a smaller portion of the team/org.  It's like those numeric usernames corps have because of some old mainframe accounting system.  Grrr.

I'd like to keep the three parts: Client, Asset, Environment.  My worry with tags is they aren't easy to scan in a list.
