Add a timeout for http download 

Download profile from AS or URL use blocking network calls
in the main thread. Set reasonable timeouts for connect
and receive.

TODO: This is not perfect as the download can still stall
in erratic links, and we have no way to abort. Ideally
we should either use Async calls and/or threads.
