E006: consistent work dir directory layout

[menzowindhouwer]

The output director in a work directory can now contain both service output as well as intermediate files, e.g., a view or editor HTML snippet. It would be better to make the directory consistent.

Example:

tmp/123/config.json
tmp/123/input/test.txt
tmp/123/output/test.xml
tmp/123/log/error.log
tmp/123/log/debug.log
tmp/123/tmp/test.html

config.json in the root. In- and output in the input and output directories. Log files in the log directory. Intermedia viewer/editor files in the tmp directory (could be purged if the service has run).
