Major Description
Improve the toleration of invalid media types. Certain common client code send invalid media type headers. For those cases, I think it's easier to just skip invalid media types or to "correct" those media types.
The two I think should be corrected:
"*" turn to MediaType.WILDCARD
"text/" (missing subtype) turn to "text/*" (or as appropriate)
The rest I think should be tolerated as invalid if possible (i.e. skip the invalid media type).
