forked from AbleScript/ablescript

BF functios can now be declared and called from AbleScript code. Function parameters supplied from AbleScript are serialized manually into byte sequences using the `BfWriter` trait, and are available from BF code using the input operator, `,`. At the moment, BF functios simply write output to stdout, and are therefore incapable of communicating results to the rest of the program; this might change in the future if we can get something close to pass-by-reference working.
