SQL Server cannot sort on type text. This causes three errors in the activerecord test suite, where tests sort on the comments.body or posts.body columns. This patch changes these columns from text to varchar(4096), allowing these tests to proceed (and pass). All activerecord tests now pass under sqlserver.  References #3581. [Tom Ward]
