Change asserts for a custom leap_assert method
Also: - Make SRPAuth and the Bootstrappers be a QObject instead of a QThread so we can use them inside another more generic thread - Add a generic CheckerThread that runs checks or whatever operation as long as it returns a boolean value - Closes the whole application if the wizard is rejected at the first run - Do not fail when the config directory doesn't exist - Set the wizard pixmap logo as LEAP's logo - Improve wizard checks - Make SRPRegister play nice with the CheckerThread
