Protect against servers with no URI scheme prefix.

Rubberband's reconnecting server finds server
names that don't have a URI scheme prefix. With

it'll error out.  This change protects against
that problem by automatically prefixing a
"http://" when no scheme is provided.

Allow multi_get to take a hash
