ImageView: oudere versies downloaden

- First of all, the drawing logic has been displaced in a custom PictureBox control that handles everything.
ImageView is basically the PictureBox control "with some UI stuff around it".
- The code logic has been separated from the UI as much as possibly by pushing it aside in a "State" class.
This is a much better and cleaner solution than what was there before (a hot mess of code in the windows form class file)
New features
- HEIC support (Apple's new default image format in IOS).
This was already baked in ImageMagick but not officially supported in ImageView. (#19)
Bug Fixes
- Images with alpha channels not displaying properly (#18)
- Changing language resets the status bar (#16)
Other changes
- All dlls are now under a /lib subfolder (#22)
Known issues
- Pixel Coordinates are wrong above 32767 (#1)
