Doc: enhance gating reference with diagrams
ASCII art is fun but not savvy for project managers and directors. This
patch slightly enhance the 'gating' documentation with colored diagrams.
This is made possible via http://blockdiag.com/ by Takeshi KOMIYA who
even took the time to write a sphinx extension. The version dependency
is at the very least 0.5.5, but might be higher :/
