2019-03-25repl: fix terminal default settingRuben Bridgewater
This makes sure that the described default behavior for the `terminal` option is actually always used and not only when running the REPL as standalone program. The options code is now logically combined instead of being spread out in the big REPL constructor.

2019-03-19tty: add NO_COLOR and FORCE_COLOR supportRuben Bridgewater
This adds support to enforce a specific color depth by checking the `FORCE_COLOR` environment variable similar to `chalk`. On top of that we also add support for the `NO_COLOR` environment variable as suggested by https://no-color.org/.

2019-03-05tty: add hasColors functionRuben Bridgewater
This adds a small wrapper around the `getColorDepth` function to check if the stream supports at least a specific amount of colors. This is convenient as the other API is not as straight forward and most use cases likely only want to know if a specific amount of colors is supported or not.

2019-03-03tty: improve color detectionRuben Bridgewater
1) Using `process.env.TERM = 'dumb'` should never return any colors. 2) `process.env.TERM = 'terminator'` supports 24 bit colors. 3) Add support for `process.env.TERM = 'rxvt-unicode-24bit'` 4) `Hyper` does not support true colors anymore. It should fall back to the xterm settings in regular cases. 5) `process.env.COLORTERM = 'truecolor'` should return 24 bit colors.
