Made changes with OutParam::OCCICLOB bacause of problems with output cirillic chars

I found a problem with output data with cyrillic chars from oracle. When output was large size (over ~2000 chars) i got unrecognized chars in clob. The settings are: NLS_LANG=.UTF8 (also tried AMERICAN_AMERICA.UTF8, AMERICAN_AMERICA.AL32UTF8.). After i made changes in connection.cpp it started work. :)
