Version bump to 0.9.1
Added checks for fragmented tables Fixed login routine to allow zero-length passwords without re-prompting for the password repeatedly Added workaround for wget 1.11 timestamping bug Fixed a math error in the temporary table calculations Fixed an error that occurred when the status variable Open_files returned zero Added table cache change in preparation for MySQL 6.x Thanks to Ville Skytta, Trent Hornibrook and Luuk Vosslamber for the bug reports and feature requests!
