Evan Shaw 75d28c083c Don't treat negative numbers as literals ...

Fixes #93.

Previously, "1 -1" was lexed as two number tokens: a positive literal and
a negative literal. This caused problems when it came to parsing.

Now the '-' and the second number are separate tokens.

Note this is a breaking change, since `-16.sqrt` is now parsed as `-(16.sqrt)`,
as opposed to `(-16).sqrt`.

There is a small bit of overhead to doing it this way, but it might be possible
to optimize that out in the compiler at some point in the future.
