- Preparation on a switch to MSVC on windows
  - Reason: Support for vcpkg, while MinGW is only community supported

- Alt + holding left mouse-button enables to move the point under the cursor by dragging it with the mouse
- Point isn't moved anymore as soon as either the mouse button or alt are not pressed anymore
- Added documentation in "Key Bindings" Window for this and for !188 (Jumping to frame of trackpoint under cursor; Alt + dbl-Click)

Add AutoSave mechanism. The manual changes to the trajectories are counted. After 10 changes, the trajectories are exported to a hidden file. This hidden file can be loaded in the case of an crash of PeTrack. The project file is saved time based.

Enables to move to a frame by clicking on a trajectory via Alt + Dbl-LClick

- Add large comment describing the approach taken
- Use OpenCV data types when possible to do explicit matrix-vector-calculations

We previously used a comparison to quality 100 for checking, if a point is a detection or not in the changed code. This was replaced by `80`, so a color-detection on e.g. a multicolormarker with code, which has quality 90, still gets counted as detection.

Also a helper function `isDetection` was created, so that this knowledge about the quality <-> detection relationship isn't scattered everywhere in the code.

There was an error, where a person, who was already deleted because they were merged with another, still got evaluated. During this evaluation, the person which got the index of the deleted one got processed, or a segmentation fault happened, when the deleted person was the last one.

This is fixed by setting `mStatus` to not only signal not being tracked, but also, already being merged away.

- Move last used export file from static var to member var
- Reset member var on opening a new project

This means PeTrack now requires C3D-files with joint positions added in. This results in a more accurate representation of the skeleton.

- Stop Tracker inheriting from QVector, instead save TrackPerson in std::vector
- Save TrackPerson's in another class (new class PersonStorage)
- Move all functions directly accessing the trajectories in a writing/editing manner into this class
- Some small refactorings and documentation-comments
