We were missing any basic tests for sending UTF-8 strings!
Also dropped some redundant comments
These are identical regexps, make the code better self-documenting. Note that ASTRING_SPECIALS is identical to ResponseParser::Patterns::ASTRING_SPECIALS.
This allows us to raise the exception during argument validation, rather than waiting until we are sending the command (which is too late to save the connection from being corrupted).

The latest release does validate that atoms, quoted strings, literals don't contain any NULL bytes. However generic string arguments would not be fully validated until they attempted to send (inside
#send_string_data).This change allows us to raise the exception during argument validation, rather than waiting until we are sending the command (which is too late to save the connection from being broken).
Additionally:
send_string_data.astring(used for generic string args) andAtom. This (or something like it) may be promoted to public rdoc in a future version.
