Originally, if WSME received an Accept or Content-Type header that
was not aligned with what it was prepared to handle it would error
out with a 500 status code. This is not good behavior for a web
service.
In the process of trying to fix this it was discovered that the
content-negotiation code within WSME (the code that, in part,
looks for a suitable protocol handler for a request) and tests of
that code are incorrect, violating expected HTTP behaviors. GET
requests are passing Content-Type headers to declare the desired
type of representation in the response. This is what Accept is for.
Unfortunately the server-side code was perfectly willing to accept
this behavior. These changes correct that.
