Add support to get and set ciphers on SSL instance.

Motivation:

At the moment it is only possible to set the cipher suites to use on the SSLContext while it sometimes is needed to set it explicit on SSL.

Modifications:

Add SSL.setCipherSuites(...) and SSL.getCiphers()

Result:

It's now possible to set and get ciphers on SSL
and remove the trailing dot (it's not a sentence, so it should not end with a dot.)
