10-06-2011 Archive::Unrar v.3.0  (the most mature and feature wide to date)

Added Test mode. The Test mode does not extract files but verifies if they are valid (i.e checks for CRC errors, if passwords are correct etc) 
Two constants has been added : RAR_TEST and RAR_EXTRACT while "process_file" subroutine's signature has changed :
	process_file( file=>$file, password=>$password, output_dir_path=>$output_dir_path, selection=>$selection,callback=>$callback,$mode=>$mode );
to accept the optional parameter $mode. $mode can be set to constant RAR_TEST or RAR_EXTRACT. If not set it defaults to RAR_EXTRACT

Made minor code corrections

Revised documentation and commented/annotate code
