Support for remote Usb2Snes Websocket server

This release adds the possibility to specify a remote USB2SnesW in case you want to use QUsb2snes/SNI/Other on another computer, while still using your applications locally. For now, you need to add "remotehost=ip/hostname" in your config file to enable this feature.

IMPORTANT, must read:
The legacy port is now disabled by default . 8080 is a common port used by some applications and sometimes can lead to some issues. Most applications now use the new port. If you used the updater to get this release, you will need to download the release to get a new copy of QFile2Snes (you can just copy QFile2Snes.exe to replace the old one) that does not use the legacy port. If you really needed it you can reenable the legacy port in the Misc menu.
