Pass through custom headers on collection requests

Request headers were getting lost when kicking off a collection request.
This will send them straight through the child buildRequest method.
I also changed the default header additions to only set the Content-Type
if it is not already set. This allows developers to overwrite the
default headers. This is necessary in OneNote to POST page content, as
they require the "application/xhtml+xml" Content-Type header.
The helper method searches for an existing header by name (instead of
the default name/value pair), since the values needn't match up.
