type implementation for detailed descriptions

Previously, description was a simple string, but supporting more complex
descriptions requires that new data be passed.

The type of a nodes description has been updated to be either a simple
string as before, or an array consisting of short description string, an
html string for the full description, and a placeholder dict for future
usage.

Definitions and usage points for description have been updated to
accommodate this change
