Safe-by-design: drizzle_queryf()

[Olaf van der Spek]

Could you add a function that makes it easier to write queries in a safe way?
Proposed syntax:
drizzle_queryf("select * from %n where uid = %d", 'users', $_GET['uid']);

%s: escape, surround with '
%n: escape, surround with `
%d: either ensure it's an int or just escape and surround

A squeryf() variant that returns the result for composition would be handy too.
