Updated IF statement

While working on examples and testing, a major bug with IF was discovered. Basically, MOD, AND, and OR weren't working with IF. Now they are. I was just forgetting that I cannot parse expressions from IF without the THEN, so I made it to where you must just use a line number or variable as opposed to a whole expression for the jump. The reason is the spaces were conflicting.

We will continue testing and ironing out bugs.
