* added new `_log` function With `_log`, the `_notify` method wa rendered obsolete. `_notify` was not completely removed due to test failures in `check-for-changes.sh`. The new `_log` function properly uses log levels such as `trace`, `debug`, `info`, `warn` and `error`. It provides a cleaner solution and renders `DMS_DEBUG` obsolete too (as only `_notify` depends on it). * converted all helper script to new `_log` function * converted all startup stacks to new `log` function * `start-mailserver.sh` now uses new `_log` function * final test and misc small script adjustments * updated documentation
