webui: send API version in RPC requests

Currently there is an incorrect behavior that server doesn't send datetime
and dnsname data in new format.

This patch adds the version to each RPC request making the UI look as  the
latest client. Server then sends data in correct format. It also removes
the "unknown version" warning from each RPC response.
