Shader:send now optionally accepts a Data object (with optional byte offset and size parameters). Resolves issue #1343.

Also changed the optional 'columnMajor' argument of the matrix variant of Shader:send and Transform:setMatrix to accept enum constants instead. Valid values are "row" and "column".
