ci: set up travis build

- use seperate plugin dirs, plugins-mac, plugins-win, plugins-linux for the flash plugin to support
simultaneous win and linux build
- enable notariziation, use env vars to run on travis
- ci runs 'yarn run dist', skip docs build from ci
- pass GH_TOKEN to docker containers
- update to latest electron packages
