Move AlignmentGridBox out of Control (Gray out calib 5/N)

See merge request !295

- Moves ui and code of AlignmentGridBox out of Control into its own class
- Changed GridItem to work with AlignmentGridBox instead of Control

Use restoreGeometry instead of pos and size

Closes #417

Install ffmpeg-plugin on mac

See merge request !312

We want to use ffmpeg as VideoCapture backend. To do this, we need to install the .so-file manually, since it is not discovered by otools, which is used by fixup_bundle. This ensures reproducibility (of regression test results).

Update ReadMe.md

See merge request !311

Resolve "Check whether mProFile is a directory"

Closes #353

See merge request !291

Resolve "Freezed GUI"

Closes #372

See merge request !293

This commit deletes the concurrent call to updateImage, since it lead to instability. Especially on Mac, PeTrack would randomly freeze and perform poorly overall; sometimes even crash. (Due to functions executed on different threads which should only be executed from a specific thread, potentially over a queued connection, i.e. signal-slot)

Resolve "Quit PeTrack"

Closes #399

See merge request !297

The Player continued to play the video after the main window was closed.
Now pauses the video once the window is closed, so that all of PeTrack
can exit.

Resolve "Clear'ing empty test tab"

Closes #411

See merge request !296

- handle special case of calling the function without wanting to delete anything
  (i.e. cound == 0)

Refactor grid item

See merge request !294

- delete dead code
- simplify existing code, e.g. by using Qt drawing utilities instead of our own

Resolve "Debug under MSVC linker Error"

Closes #225

See merge request !292

Since OpenCV is quite slow in debug, we always link against the release version. This does not work with MSVC due to incompatible crt's. Therefore, we don't do it on MSVC and have to live with the slowness...

Merge branch '227-add-script-which-checks-if-license-header-is-added-to-new-source-files' into 'master'

add script to check license header

Closes #227

Add extra tab for trajectory tests

Closes #214

See merge request !141

Allows to display the result of the current plausibility checks, e.g., inside ROI at begin or end, short trajectories, equality to other person or fast velocity variations, in a table. Clicking on the table jumps to the person(s) and frame of the failed check. A color encoded column shows if the issue was already resolved. The color will be automatically adjusted when a person is changed.

Gray out calib 4

See merge request !284

- that means moving the widget and all its signal/slot connections
- Create new interface `WorldImageCorrespondence` for all calculations between image/pixel coords and world coords (dispatches to `ExtrCalibration` when 3D, else uses old 2D coord sys)
- Moves the methods for wold image correspondence from the `ImageItem` to the newly created `CoordinateSystemBox`
- During this change: Make the 2D coord system not depend on `mapToItem`; its now using normal affine transformations (`QTransform`) instead, which incidentally should make #383 easier
- `imageSizeChanged` is now a slot of `Control`, such that `ImageItem` can call it without having a reference to `Control` by sending a signal (Following that: image item is now now directly depending on control anymore)
- Some include clean-up

Resolve "Custom buttons in PMessageBox"
