Changelog

- OpenFlipper 4.0 ( 05/03/2019 )
  - Breaking changes
    - Picking functions use size_t instead of unsigned int now (Required to get rid of a lot of warnings during compilation)
    - Enabled AUTOMOC in cmake for QT ( If you get redefinition errors, guard the corresponding headers with a pragma once ; If you get gl.h before glew.h errors, move your widgets not using OpenGL into a subdir and add that to the DIRS macro in your CMakeLists.txt)
    - Enabled AUTOUIC in cmake for QT ( If you get trouble finding generated ui_*.hh headers, change your include to ui_*.h to get them generated correctly)
    - Removed a lot of Scenegraph includes in BaseObjectData to reduce gl qt collisions and replaced them with forward declarations. (You have to include the scenegraph headers yourself now!)
    - Removed a lot of unnecessary large QT includes from the Interfaces (Mostly QtWidgets). You have to add your own include statements in your plugins now.
    - Removed WhatsThisGenerator include from BaseInterface. You have to include it in the plugins now if you use it.

      - sceneGraphUpdatesBlocked()
      - blockSceneGraphUpdates()
      - unblockSceneGraphUpdates()
    - Bugfix: Fixed undirected shooting function returning wrong nearest triangle (was always the one with the most negative distance) in BSP
    - Interface: RayCollision is now a sorted vector conbining standard pairs of the hit handles and their distance to the hit
    - Interface: Render Interface: Implemented capabilities check for renderer interface
    - Interface: ACG, Renamed the basecolor functions in the core to defaultColor
    - Bugfix: Emit object updates for all objects in scene, if -1 is given as updated object. (Should not be used, as it is very slow for a large object count!)
    - Logic: if an object gets deleted, no updatedObject (-1) signal will be emitted now. Use the objectDeleted slot from LoadSaveInterface.
    - Build: Default to relesae build type by default
    - Interface: Changed selection interface the qicons have been replaced by QString. The path to the icon has to be given now This avoids the problem of qpixmap creation in the selection plugins, when no gui is present Added deprecation warning, to informa about deprecated plugin interface usage
    - Interface: Don't emit updatedObject(-1) anymore if an object gets deleted. Use the slot objectDeleted from LoadSaveInterface instead.
