Small changes in requesting service from enigma that may help with
"difficult" services.

- better (clearer wording) logging
- stretch timeout to 60 seconds
- poll enigma more often for quicker response
Revert "Change authentication configuration according to OpenWebif usage."

This reverts commit f0ff65295ff1dbb80198dfe7e95de1b9032fc500.

It seems the openwebif configuration options:
- use http authentication
- use authentication for streaming
do not do what they suggest as seen from streamproxy's perspective.
