Cast issues

> Also, qss will attempt to typecast Boolean and Number values.
Is there a way to this feature be optional? I'm facing issues with unwanted casting. Strings like '0101' or document numbers that starts with zero are being casted and must be handled padding zeros.
It would be nice a parameter indicating if should cast.

Start by reading the qss querystring encoding and decoding entry points to understand where Boolean and Number casting occurs. Define how an optional casting control should affect values such as '0101' and zero-padded document numbers, then verify the behavior with focused tests; the issue does not name existing files or tests.
