Overwrite server.conf settings only for provided env vars (#76)

* Overwrite server.conf settings only for provided env vars

Currently on every start the whole server.conf file gets replaced which causes any changed settings during runtime to get lost

* Fix readme formatting

* Add "webUIEnabled" env variable

This is the only setting that can not be changed via the UI

* Remove default values from readme
