added: get_text, get_blob, get_inet, get_varint. Thorough testing of deserialization and insertion of these datatypes.
Update cql_cluster_impl.hpp
Update cql_connection_impl.hpp
Merge pull request #31 from stanislav-podlesny/master

Fixes for Cassandra C++-driver
using cql_uuid_t in get_uuid, using cql_host_t::ip_address_t instead of string. Correction of coding style.
added deserialization from VARINT to boost::multiprecision::cpp_int. No limit to the length of the value.
Enabled NULL values in prepared statements.
get_varint. Small correction of layout and coding style. Removing comments in Polish.
Minor fixes.
Update cql_connection_impl.hpp
Update cql_connection_impl.hpp
Infrastructure for compression support
binding new two types: cql_uuid_t and boost::asio::ip::address for prepared statement.
Switched from raw pointers to boost::shared_ptrs in message parameters.
Merge pull request #32 from omikro2n/nullvalues

Enabled NULL values in prepared statements.
