Clean up eval_expr some more

I keep going back and forth on how I want this block to look :P
Anyway, this is *probably* its final-ish form, until the parser gets
re-written.

Use impl Value rather than trait BfWriter
...
It probably makes more sense to be writing values with
`Value::bf_write` than to go for the complexity of using a trait to
allow `Writer::write_value` (which also looks ambiguous because it's
not immediately clear that a generic name like "write_value" relates
to BF or AbleScript).

Add Brainfuck functio interpretation
...
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.

Fix panic on arithmetic error
...
Divide by zero and add, subtract, or multiply with overflow are all
caught now and reported as an ArithmeticError, rather than causing the
interpreter to panic.

Currently `overflow_should_not_panic` and `variable_persistence` both
fail due to bugs in the interpreter.

Added variable declaration, `if` statements, `loop` statements,

declarations, brainfuck declarations, function calls, and the control
flow operators "break" and "hopback".

The expression `sometimes & true` now evaluates to `true` 50% of the
time and false 50% of the time, rather than throwing a type error
