MssqlTextExpression class abstract mixin

An expression whose SQL type is text, and which the text predicates accept.

A marker rather than a class, so that a column, a CONCAT and an untyped Col('Name') can all be one without sharing an implementation. It is what keeps total.contains('5') from compiling: a numeric column is not one.
