* VM Signals are used by running functions to dictate whether a function
should return, or if it should call another function. These signals
can be injected at any time allowing for user functions to inject
themselves at runtime.
* obj::Method is gone since it's not being used yet.
* Obj impls must implement as_any(&self) -> &dyn Any now. This allows
for UserFun and NativeFun to be explicitly cast (among other things,
in the future).

* Variables were previously named "Local"s because they described a
local variable - however, this is kind of a misnomer because it
handles globals as well. This has been changed pretty much everywhere
when appropriate (hopefully).
* Renamed obj/names.rs to obj/reserved.rs, freeing up the "names" module
for the new Names handle
* Renamed obj/locals.rs to obj/names.rs, see above

* Basic are a more linear way of representing code. Thunks beget basic
blocks, which beget vectors of instructions.
* Basic blocks are also being flattened into a vector of instructions
(hopefully, no tests done yet)
* OH yeah locals can be collected too (but currently are not being
collected in the compiler, that should come soon)

Some instructions are currently implemented. Others are not. This is
mostly just a checkpoint so I can implement lexical name definitions.

While I like the idea of having a runtime completely decoupled from the
syntax and compiler, I don't think this is that big of a project for
that to be necessary or even useful yet.
