fixed the bug of wrong indentation 

the line https://github.com/OpenPTV/openptv-python/blob/master/pyptv_gui/pyptv_gui.py#L585 is incorrectly indented and has to be shifted 4 spaces to the left. This bug caused us to run the correspondence n_camera x n_img times instead of n_img times only.
- there was an indentation based bug in Python, that caused Sequence to run several times over the same image
- other files barely changed - maybe space here and there.
