[cas-dev] case sensitivity for RegisteredService matching

Because we're using Ant Pattern Matching to match URLs (and not
octet-by-octet comparison as we can't), I'd be fine to do the entire
comparison as case insensitive to meet the requirements for the hostname and
scheme.

Does that seem reasonable?
