Move the glossary to a separate file
Currently we have an insignificant glossary at the end of the design-2.0document. This patch moves it to a separate file with the goal that itwill grow and all files can refer to it.
Some small doc updates
We change some formatting to sphinx-specific, to show how thedocumentation can be improved.
