major update:
- remove threading overhead by resorting to an event driven design with mio as a backend for epoll
- Clients can now have an arbitrary amount of ip adresses and lan-mouse will automatically choose the correct one
- -> seemless switching between ethernet and wifi
- cli frontend + frontend adapter for future frontends
This allows to dynamically add clients when an event is received from an unknown IP address.
The user is asked to confirm any unknown connection from new clients.
Currently the back-ends for event producing and consuming are not yet notified, so events will not be received and sent to the newly created clients.
* cleanup Cargo.toml
* exclude backend from windows build
* remove env include in windows build
* remove Backend from windows build
* fix compiler warning
