Better assert(), move some Win32 functions to DQN 

Asserts are now more defensive and diagnostic. Initially asserts provide a hard
break in the program, and the intention is to disable asserts for release.
Having experienced bugs in release mode due to optimisations with asserts off
there's little protection against errors that occur in release mode since all
asserts are off.

Now asserts can be used in release mode whilst still evaluating the expression,
and allowing user messages/diagnostics to console.
