- FIX: guy crashed when autoreload with no static folder

- EVOL : autoreload available

- BIGGEST CHANGES:
- "real instances" (no more clonage) .. a lot simpler
- better system to manage instances (same fo embbeded or redirected)
- pyside: each window now have a reference (.parent) to the main instance (the one which starts all)
- a lot of little fixes
- more pytest coverage (mainly main features)
- _render() -> render() and replace "guy.js" in all cases
- resolve query params when redirecting to another instance for match the constructor

- EVOL: Py side : can call js method directly ( `await self.js.jsmethod(...)` )

- FIX : trouble to find config folder when symbolic link used
- EVOL: "init" can now be async too
- FIX: the right "init" is now called when a instance is created (on ws call)
