This bug-fix release includes two minor fixes regarding the usage of ActiveSupport and in the logging code. Thanks to Toby DiPasquale for providing a bug report with patches!

Right_aws now no longer has a "require ActiveSupport" statement. Instead, if ActiveSupport is already loaded, it uses its CoreExtensions, else right_aws defines these core extensions. This avoids loading all of ActiveSupport just because it happens to be installed on a machine. This caused conflicts.

Right_aws now properly passes an optional logger down to right_http_connection.
