Tidy up wiki entries for SSL

Nik, can you look at the 2 wiki entries for SSL and improve them? The Configuring SSL entry is a port from jetty5, so can you confirm the information is still relevant, and also skips around between talking about SslSelectChannelConnector and SslSocketConnector in the examples - we need to make a) the distinction between the 2 clear and b) be consistent. The entry on the SslSelectChannelConnector is lacking in detail - can you provide more information, a comparison with the SslSocketConnector etc? Thanks.
