State sharing between Python and Javascript

[r0x0r]

The next major version of pywebview will introduce state - a way to seamlessly share data between Python and Javascript. State is represented by the pywebview.state object in Javascript and Window.state object in Python. Updating a property on either object will update its value on the other side. An example can be found here.

Additionally, each state object emits an event when state is updated. Implementation details are not set in stone, but currently the syntax is pywebview.state.addEventHandler('change', handler) and window.state += lambda key, value: pass

State is implemented by means of a proxy in Javascript and an observable class in Python.

The current ahem state can be tracked in the store branch
