Novo Player - Linux

What's New:

- Added session management of a running openMSX (reset, mute/unmute, pause, fullscreen and emulation speed)
- Added ability to use openMSX's trainer feature to enable cheats
- Moved the default user data and settings to a different folder. All data will be migrated automatically, and the old folder ("%userprofile%\Novo Player" on Windows and "~/Novo Player") can be deleted manually afterwards
- Allowed to store user data and settings in the local folder (for portability) - similar to what Dolphin emulator supports (Feature request)
