NETSCRIPT: Add undocumented function printRaw() (#277)

This is analagous to tprintRaw (enabled by ns.iKnowWhatImDoing()), but
for logs instead of the terminal. This provides a supported* method of
creating complicated UIs for scripts.

*No actual support, expressed or implied, is provided for use of this
function.
