* Double quotes not needed by docker compose
Same issue as here https://github.com/zokradonh/kopano-docker/issues/216
* move deletion of tmpfile into an exit trap
otherwise the file is not cleaned up when supported images are built
* repair sourcing of env by removing kopano ldap settings from env before sourcing
* additional packages env vars should be quoted in .env
* adapt start scripts to handle quotes additional packages
* treat update-tag script with ldap variable fix from setup.sh
fixes#216
* run version.sh in travis (to fail early if something is wrong there)
commit forgotten fixes to start scripts
* replace bash function to list docker tags with https://github.com/genuinetools/reg/
* this depends on new release in https://github.com/genuinetools/reg/issues/186 to fully function
* update docker version
* fix version.sh to also show versions from repos defined in .env
* add script to list available tags and update values in .env
* define default values for all version vars
* add previously missing containers
* use command instead of hash in update env script
* use a custom select function instead shell builtin (since it does not handle default values)
* add setup-update-tag in test.exp
