treewide: use number prefixes for lighttpd configuration files

The lighttpd now prefixes the configuration files with numbers to ensure their ordering. We should use this as well and this changes names of all our lighttpd configuration files to be prefix with number.

The rules used here is:

80: any regular web service

70: dependency of other web services (just as API not for configuration)

60: root configuration (change to 90 proposed - see the discussion)

50: dependencies for other services (variables required for configuration)

45: the conditional modification of basic Lighttpd behavior

40: the SSL enable (modification of basic behavior)
