Add DNS Server, Many Other Fixes/Enhancements (#12)

* Add 443 just in case since docker ps is showing it as active.

* Add two new projects.

* Add pre-testing content for DNS.

* Initial untested stab at the GitLab config.

* This project uses build, image name is not needed.

* Cleanup, untested guess at how to handle the variables in the pipe section.

* Filled out all files for DNS. Ready for testing.

* This seems to work, Ubuntu is hoarding port 53 though even though local services are shut off.

* `dnsmasq` container is testing successfully now.

* Don't allow a run unless the config files exist.

* Correct the crontab entry so that $RANDOM works correctly.

* Certs were not being saved by LetsEncrypt for Nginx correctly. Should be working now.

* Do not allow disabled folders into Git.

* Do not allow disabled folders into Git, 2.

* Do not allow disabled folders into Git, 3.

* Do not allow disabled folders into Git, 4.

* Do not allow disabled folders into Git, 5.

* Do not allow disabled folders into Git, 6.

* Don't add logs from anywhere.

* Add ping and dig to Nextcloud container for troubleshooting.

* Fix tabs.

* Make unfinished suffix consistent.

* Clean whitespace.

* Multiple names for a single IP address.

* Add 2nd example domain from hosts file.

* Add caching program Redis for Nextcloud.

* Add REDIS_HOST variable for automatic setup through config/redis.config.php.

* Upgrade to compose version 3.

* Move OnlyOffice to Nextcloud area.

* Change container name.

* Add container_name to all compose services.

* Shorten names for Nextcloud services.

* Comment possible OO fixes while trying to get container to use DNS.

* Remove OnlyOffice setting tests.

* Do not commit .env files, only their examples.

* Move OnlyOffice to be its own configuration again. Add sourcing of DNS settings so that local traffic routes correctly.

* Fix source file, BASH_SROUCE did not work without the shebang. Also fix bug for when it sees `..` and assumes current directory.

* dns.env file did not work out, env_file: element not being read before dns: element. Using folder-specific .env files instead, seems to be loaded before dns: element. Also move other values to the env files for better password privacy.

* Keep commands for cleaning up environment in one file.

* Update examples.

* Fix cd moving the user to the file's directory.

* Add note for user to set up the env file.

* Replace README files by unhiding the example files.

* Still need to specify the variables in the environment: element.

* Add header variable.

* Place host above database.

* Fix "JWS" typo.

* Do not use the HEADER parameter.

* Add vim to fix packages.

* Forget about the manual DNS servers for a minute, ensure host is set up properly first. Ubuntu is happy but Debian is not.

* Try using the host network explicitly.

* Temporarily give up on having Nextcloud server see local OnlyOffice server. Works when they are different machines but need them together.
