Initial code for Shared Secret (POST /devices verification not done yet)
Fix Auth issue for GET FILE (dont pass Authorization in header)
Add verification of Server Sig
Fixes for BuddyClient/Impl in ServiceClient
If Server does not send a signature for POST /devices then dont fail even if we have a shared secret configured
Not sure I like the previous checkin. The whole point of server sig is to validate the server. This could leave apps open to fake servers. Reverting it for now
