[chuck-dev] for loop, empty conditional statement, possible fix

Hi Kassen,

I would not go scientific here... :) I just wrote down a line of code 
which I expected to work... However, I've  never written down anything like:

if() {} or while() {}

which I suspect would give a C compiler error.

My point is that the first and the third part of the for() statement can 
be omitted as for now (in ChucK). So I don't see a point why the second 
one shouldn't work the same way.
