Modify client to handle clock skew for If-Modified-Since header

Some client may have an incorrectly set clock. This can cause duplication of campaign messages or some campaign messages not being seen by the client.

The requested work-around is to have the client echo the "Date" header contained in the server response back as the "If-Modified-Since" header.

This looks good on rnewmans test build.  I set the device clock forward several hours. I still get the announcement.
