Fixed build warnings and undo changes

- Build problems:
    - Qt 5.13 obsoleted some calls that were used in our Qt library.
    - The PhilipsHueLight and PhilipsHueBridge classes did not use the private logger class
- Undo changes:
    - In Commit e6c2e7e, I made changes that were not covered. An apology goes to @b1rdhous3
