Corrected Markdown syntax errors, reorganized Console UI section

* Corrected an instance where an example html tag was not placed in
backticks.
* Reorganized the Console UI Terminology to not only correct Markdown
syntax (some lists were not displaying as lists), but to make the whole
thing into a series of hierarchical lists.
Merge pull request #214 from holguinj/master
