This allows filter groups to be intermingled with other filters using the '{groupName}' syntax proposed by kenkendk.
It also means that when the filter that caused a file to be ignored is reported, it can report the name of the group, rather than a large and unreadable list of wildcard and regex patterns.
This is still missing several things (better documentation, removing the old --default-filters parameter, updating the UI), but should be another step in the right direction.
There might also might easily be other side effects that I haven't considered here that will need to be teased out and fixed.
