FIX Config wasnt filtering wildcards properly

Browse Source 
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.

See http://open.silverstripe.org/ticket/7765 for more
