- Initial Travis-CI integration
  + Adding build configuration with dependencies against Ubuntu 12.04
  + Updated README to contain build status image
  + Updated ignore to support dependencies
Fix seg fault on overloaded connection (CPP-167)

Improper static cast and use of pointer in timeout callback
Also removed unused parameter in Pool::maybe_notify_ready()
Add NULL check to cass_value_get_*
- Updated CMake configuration
  + Add preprocessor definition to ensure Boost does not use rvalue references (this allows the integration tests to build without c++11).
  + Added a check to validate CMAKE_CXX_COMPILER_VERSION variable existence and added a workaround to get the compiler version from gcc (CMAKE_CXX_COMPILER variables were not added until 2.8.x)
  + Ensured the LIBUV_INCLUDE_DIR discovered by the parent was used for the unit tests (fixes unit test build)
- Changed INT64_MAX/MIN to use c++ numeric limits
- Updating TavisCI configuration
  + Install libssh2 and build Boost v1.55 from source
  + Build tests and run unit tests (increases build status information)

NOTE: CMake configuration needs some more TLC to work properly on CentOS5.  The LIBSSH2 package available by the default yum repositories is v1.0.0 and method calls used by the integration tests were not available until v1.2.5.  CMake configuration should check for LIBSSH2_ROOT_DIR similar to LIBUV_ROOT_DIR.
- Correcting the creation of the softlink for libuv
- Silencing some of the output for Boost b2 install
Silencing another directory change to help with navigating through Travis-CI output log
Updating the NULL test case to check for CASS_ERROR_LIB_NULL_VALUE when using the appropiate cass_value_get*() function
