Improvements and bugfixes

– The new virtual camera still had some timing issues. No its stabilized. When operated with no fps limit, the video files is processed at maximum possible speed, not the recording speed. It is good to have a fast computer for this kind of work.

– The eventer preview ran bumby in some situations. THis is now fixed.

– Sending Emails did not work with lots of large images attached. Now it does.

– There was a problem in the trainer. Some jobs got stuck. Now they all go.
