Fix REST API for WSGI Add dictionary-like headers attribute. Similar to the apache implementation in same directory but we look up the given header in the wsgi environment. Environment entries are mangled (all uppercase, '-' replaced with '_', prefix HTTP_). So on lookup we mangle the given name first. This allows the rest implementation (and others) to look up headers.
