better handling of auto color mode

- deciding whether to use no-style when there's no --color argument is made twice:
     for app running and for export when leaving
- remove the deprecated `--no-style` launch argument (use `--color no` instead)
- deprecate the `--out` argument (redirecting the output is the recommanded solution)

Fix #397
