Hi Dev's,

Any objection about using MEDIUMTEXT() instead TEXT field type in "vars" field of session table?

TEXT type allow only 64KB session strings, but it can be larger under certain circumstances like big search results. In a search test (using search box) that returns 4k messages, my session string [1] exceeded the column's maximum length and the value is truncated. It broke the session system and send the user back to the login screen.

If nobody has any objection, I can provide the patch.
