The zero value of Value is now defined to be undefined
...
Previously, it was a publically accessible but invalid value (valueEmpty).
* Deprecate internal use of UndefinedValue(), NullValue(), FalseValue(), TrueValue()
* Guard against Empty, Result, Reference values from escaping the package

Simplification & refactor of (parts of) the runtime
...
* Proper lowercasing for internal stuff
* *Environment => *_stash
* ExecutionContext => _scope
* Simpler & shallower call/construct mechanics
* Remove unnecessary fields & methods
* Better scoping (no more stack): []*_scope => _scope.outer
* Some speed improvements
In preparation for #66

Skip unexported fields, begin json.Marshaler support
...
* The "reflect" package is willing to expose unexported fields in structs (a little suprising).
* Skip unexported fields when enumerating or trying to access (pretend they don't exist).
* Allow structs that implement json.Marshaler to work as expected in a JSON.stringify call.
If we let the runtime try to access unexported fields, it'll cause a panic.
This fixes #64
