fixes #166 Websocket TLS mapping

This introduces the wss:// scheme, which is available and works like
the ws:// scheme if TLS is enabled in the library.

The library modularization is refactored somewhat, to make it easier
to use.  There is now a single NNG_ENABLE_TLS that enables TLS support
under the hood.

This also adds a new option for the TLS transport, NNG_OPT_TLS_CONFIG
(and a similar one for WSS, NNG_OPT_TLS_WSS_CONFIG) that offer access
to the underlying TLS configuration object, which now has a public API
to go with it as well.

Note that it is also possible to use pure HTTPS using the *private*
API, which will be exposed in a public form soon.
