[Ken Roberts]

PJLink2 Update U

- Fix projector S_ON status icon selection
- Remove unused status items (status icons changed to FA)
- Fix projector icon status update for network errors
    (keep error icon until network reconnects rather than disconnect icon)
- Fix colors to projector toolbar connect/power icons
- Fix toolbar select input icon not always enabled after selecting/connecting projector
- Add max-line-length option for flake8 tests in setup.cfg
- Fix projector tests
