Restored default delay

Re-enabled delay for default mapping.

Temporarily default delay 0

Set default delay to 0 to prepare for downtimes during cluster reloaction, set delay for google to infinite with bypass, added google for other domains, renamed google room to "domain.toplevel".

Infinite delay for google

Added an infinite delay with bypass option to the google config. Reason: too many users on google.com, google.de. Many start pages (Firefox) and people whi search something but without a common interest.
