* wip [skip ci] update
* wip [skip ci] update test
* [skip ci] fix env var
* bump sinon, create helper utility to always throw when a stub is called without being given stubbed behavior
* update failing specs
* fix some error messages
* update snapshot
* warning -> note, add snapshot tests
* change snapshot os.release, test env vars
* cli: fixes#838 start cypress in dev by routing through the CLI
- matches how we run in production better to keep parity and consistency
* cli: add coerceFalse for clarity
* cli: add global flag, update to work with windows
* server: bring into parity with root scripts
* cli: just execute start script directly to work with windows
* cli: if colors are supported then force them via env vars
- this fixes windows not displaying colors from electron because by
default isTTY is false (due to electron)
* cli: fixes#921 don't ignore stderr, inherit stdio on everything except when linux + xvfb
- filter out stderr messages coming from Xlib or libudev (from xvfb)
* cli, server: force stderr tty so that normalize tty behavior when piping
* server: drop in supports color so debug outputs more colors!
* server: remove empty line
* root: refer to cypress not monorepo
* cli: make util.supportsColor return boolean
* cl: add tests around spawn behavior with forcing colors, tty, and stdio configuration
* cli: handle xvfb onStderrData callback to output debug information
* cli: handle non zero exit code error from xvfb with special message
