Watchgha

- GitHub Enterprise is supported via `GITHUB_SERVER_URL` and `GITHUB_API_URL` environment variables. Thanks, [Colin Marquardt](https://github.com/nedbat/watchgha/pull/21).
- Fix: in unusual cases, GitHub can return strange statuses for job steps. Those are now displayed as question marks.

- Fix: steps can be in a "pending" state, and are now displayed with a dot instead of "pending".

- Fix: don't fail if a .netrc file can't be found. Fixes [issue 18](https://github.com/nedbat/watchgha/issues/18).
- Fix: in the odd case of duplicate remotes, don't list workflow runs twice. Fixes [issue 19](https://github.com/nedbat/watchgha/issues/19).

- Now all GitHub remotes are checked for jobs. Previously, only one was checked, so you wouldn't see jobs running on an upstream fork.
- Added option `--only` to limit which workflows are displayed as requested in [issue 17](https://github.com/nedbat/watchgha/issues/17).
- The output is now redrawn immediately when the terminal window is resized (on Mac or Linux). Thanks, [Bill Mill](https://github.com/nedbat/watchgha/pull/14).

- Implicit .netrc authentication stopped working, but has been fixed. Thanks, [Rob Weir](https://github.com/nedbat/watchgha/pull/11).
