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
