[phobos] pull request statistics

[Brad Roberts]

Since we moved to github...

            total  open
  dmd        615    58
  druntime   396    14
  phobos     132    25

Of the open requests, the pull auto-tester stats.

            pass  fail
  dmd         36    22
  druntime     8     7
  phobos       9    16

fail == at least one platform fails to build
pass == so far, this pass of the tester, nothing has yet failed

At least linux/64 has run for each pull request.  Three of the tests will likely convert from pass to fail when other
platforms catch up.  Personally, I'm not worried about the ones that fail all that much as there's still plenty to do
with those that do pass.  Just reporting on the statistics.

Later,
Brad
