Random sort

I wrote a small patch for SMW. It allows to sort query results randomly.

Just write "|sort=random" in the {{#ask}} params.

It's compatible with other sorting, which means you can sort ascending by one property and then sort randomly by an other property.
{{#ask: [[test::+]][[check::+]]

?? test? check
sort = test, check
order = asc, rand
limit = 3


It uses the MySQL RAND() function [1], which may not be very efficient on a large number of row [2].
I hope this will be useful. Feel free to add this patch to the SMW development repository if you want.

Column Prototype
This is a very early prototype of a persistent column. It is not expected to work yet, and leaving it open will activate other new features which will break things. Press "\" (backslash) on your keyboard to close it now.
