Inaccurate order and orderby values for sortable list table columns

[johnbillion]

WP_List_Table->print_column_headers() detects the 'order' and 'orderby' parameters using $_GET. It should use the values from the actual query object instead.

Example: I have a custom post type that has sortable columns. The default values for 'order' and 'orderby' are overridden in the parse_request hook. WP_List_Table->print_column_headers() ignores these values and just uses the $_GET values. This results in incorrectly highlighted columns.

Patch coming up.

Ah you got in there before me nacin.

I'll scrap this actually, it breaks column headings for sortable columns that sort by meta_value. You can get around it by overriding the $_GET values instead of overriding the request in parse_request and everything works nicely.
