Fix a number of bugs preventing the with-scope test from working at all:
...
1. We no longer implicitly return Undefined unless we're specifically returning from a function (this also keeps actions from filling the stack with Undefined)
2. With scopes are now always inserted behind the current set of locals rather than overriding them
3. `ActionSubtract` now subtracts (instead of adds)

Move `this` into the activation object.
...
Also, change the implicit `this` on functions to `active_clip` as per the `ActionContext` docstrings.

All activation frames share the same stack (and can see each other's garbage).
