- new imgur upload interface.
- rework for a better code structure. It still needs another change separating the Controller from the code dedicated to export data to the system.
- created the concept of "worker", component used to do some work based on a screenshot.
The controller class has some important methods which may be
required in multiple parts of the code. Now that class is a
singleton (that may change in the future).
The core parts have been moved to src/core.
Now the tray Icon can be disabled by the controller.
I need to reimplement a new notification system due to its
dependency with the tray icon, they are disabled in this actual
commit.
