fix: No game path (#24)

* [refactor] moving main.setPath listener outside start method

* [refactor] setpath tells if game path is set or not

* newpath event tells if game path dialog is successful or not

* [feat] main window will not show if path is not set

* [feat] viper displays a dialog and exits if no game path was prompted

* [fix] viper prompts for game path if viper.json:gamepath is not set

* [feat] translating gui.gamepath.must key

* code cleanup

fixing single quotes and alike

* fix gui.gamepath.must message
