* Add handling for holding down media shortcut keys
* Added handling to not send through DDC commands for values which had already been set
* Moved DDC reads and writes onto the main thread
- FIXED: Issue where changing brightness back from 0 wouldn’t restore previous contrast value
- FIXED: Restoring saved contrast value across app restarts
- FIXED: Issue where using the brightness slider wouldn’t adjust contrast
- FIXED: Issue where setting brightness to 0 after it was already 0 wouldn’t restore the previous contrast setting
- FIXED: Issue where trying to use the “true” mute command on unsupported monitors would cause the mute/unmute key to do nothing
- FIXED: Issue where “0” chiclets would be shown when the step value was less than the value of one filled chiclet but greater than 0
- CHANGED: OSD-based value system to map small increment chiclet count to available range of DDC values and regular increment count to 16 available filled chiclets
- Removed whitelist which caused some issues for some people #105
- Added `hide OSD` option to `AdvancedPrefsViewController`
- Added `Longer Delay` option to `AdvancedPrefsViewController`
- Added `PollingMode` and `PollingCount` to `AdvancedPrefsViewController` (should help #37)
- Added option to reset all preferences to `AdvancedPrefsViewController`

PR #59 with enhancements and fixes (Changes done by @JoniVR):
- Code migration to **Swift 4.2**
- **Fixed** the **MonitorControl scheme** which was gone for me
- **Updated the screenshots and readme**
- **Added a feature that detects the default sound output device and only intercepts when an external display is set as default output**, so Airpods, internal macbook volume and other non-monitor devices will be ignored (#48, #15)
- **Fixed app unresponsiveness and high CPU on launch** (might be related to #50, #37, please do keep in mind that on initial launch there will still be a little unresponsiveness because the underlying framework - called [ddcctl](https://github.com/kfix/ddcctl) - attempts to read your volume settings 10 times)
- Added a **version and build number** to the main preferences panel:
- Added a build script that increases the build number on each run. Version number still needs to be set manually.
- refactored some parts of the code to make it a bit more readable.
