iglass 1.1.1

Fixed

• --app-settings and --default didn't notice iTerm2 was running when run from inside
  iTerm2: macOS pgrep leaves out its own ancestors, and iTerm2 is one of them. The change
  was written while iTerm2 was open (so it could be overwritten when iTerm2 quit) and iTerm2
  wasn't restarted. iglass now uses pgrep -a, and the tests' stand-in behaves like the real
  pgrep so this can't regress unnoticed.

Upgrade: brew upgrade iglass, or rerun the install script.
