Manual fixes and cleanup
The _config/route rules explicitly mentioned framework by module name,
so if you installed framework in the older sapphire directory youd
always end up with cyclic config requirement errors
When specifying a specific before rule and a wildcard after rule (or
vice versa), the config system was filtering out any fragment
from the list of fragments that matched the wildcard if it matched
_any_ componenet of the specific rule, not all of them.
Fixed, and added handling of two semi wild-card rules, where a
rule with less wildcards wins over a rule with more.
