Hi Ben, Joachim and devs,

I updated the following:
  * page 7: update "committer flow" to "direct commit"
  * page 9: add a simple diagram for the various ticket states
  * page 10: update ghc-proposals flow
  * page 13: correct "Arcanist"
  * page 13: add "travis"

Here is Rev.2016-Oct-30:
  GHC development flow
   http://takenobu-hs.github.io/downloads/ghc_development_flow.pdf
   https://github.com/takenobu-hs/ghc-development-flow

Please teach me if I have misunderstood, especially page 9.

Regards,
Takenobu
