* RuntimeSpanError was an extraneous solution to adding spans to the
errors; so instead this behavior has been delegated to the
RuntimeError itself.
* Usage of Inst has mostly been replaced with SpInst so if an error is
encountered, we can spit out where it happened in the source code
(hopefully with a stack trace).

This allows us to write out errors that follow the call stack and give
locations to where errors originated.

This is the path to the location that this span is pointing to. This is
usually going to be a file path, but it can really be anything you want.

This helps split up expressions, meta calls (like includes) that can be
expanded into more expressions.

We're turing-complete, babey!
* Call stack for functions now differentiates between native and quote
calls
* Better API for builtin functions allowing for more control
* Example showing off branches

* crate::scope instead of crate::syn::word, which makes more sense
because scopes are not really used in syntax at all
* Reference-counted BuiltinFn values are available for creation now

Nothing fancy yet. This commit adds a bunch of stuff (oops):
* compiling code
* VM with instructions
* remove eval.rs and just eval in the Machine struct itself
* squash most warnings now that we're using stuff here
And probably more. But that's all for now folks
