When holding down a mediakey, we'd get stuck inside the specific keyRepeatTimer block in the display loop. This caused only one display (the first one in the array) to be controlled while holding down a mediakey.
* Changed mute command from '0 speaker volume' to 'true' mute (0x8D)
* swiftformat changes
Swiftformat does this by itself so I figured might as well commit it
* Update to Swift 5.0 and run `swiftformat`.
* Refactor `MediaKeyTap` start/restart.
* Remove useless comments.
* Reorder files.
* Add German translation.
* Switch to Carthage.
* Use `DDC.swift`.
* Add `NSScreen` extension.
* Simplify menu layout.
* Hide the display’s built-in OSD.
* Fix launch at login helper.
* Fix `quitClicked` connection.
* Refactor build phases.
* Use `os_log` instead of `print`.
* Use more specific check for `minReplyDelay`.
* Add whitelist.
- Refactoring of the way the slider are created
- Read the current value of ddcctl monitor after launching the app, so no more value at 0 for the sliders
- When there's only one monitor, display it directly, not in a submenu, closes#10
- Added a "start at login" helper (still need testing) for v1.2
