Casting to an integer should be considered input sanitization

[JDGrimes]

I think this is true in the XSS sniff, but not in WordPress.VIP.ValidatedSanitizedInput.

For example:

$var = (int) $_GET['some_var'];

This will be flagged, but it shouldn't be.

It looks like #205 fixed this when the case is similar to my original example:

$var = (int) $_GET['some_var'];

However, the cast is ignored when the value is in a function call:

$var = some_func( $some_arg, (int) $_GET['some_var'] );

In a case like this I get the non-sanitized input var error.
