Befunge code golf solution

Here's my code golf version with Befunge-93, now down to 34 bytes!

It's *just* within the rules, it might look like a string literal but it's actually loading each byte onto the stack individually. Of course, Befunge has no idea about functions etc either.

All of the examples print correctly: `g('al')` -> `gal`, `g()()()('al')` -> `goooal` etc
