Fixes for #26837: MPEG Preseek does not work for some h264 files.

- Display running job template in all sequencer modes
It was displayed only for sequencer mode without preview.
- Fixed proxy rebuild progress indicator
It was alsways zero because of incorrect rounding.
- Fixed timecode saving on windows (and probably some other platforms)
It was caused by incorrect opening file for writting -- it should
be opened in binary format "wb". This error caused incorrect
movie duration detection on windows.
- Fixed movie resolution detection for some movies.
In file attached to report, Blender detected resolution 1920x1088
instead of 1920x1080. Not sure if this fix is correct or it's
issue in FFmpeg, but it's something what mplayer using: store
width/height before running avcodec_open().
- Fixed frame number calculation when building timecodes.
It was rounding error caused some frames be positioned incorrect
in several cases (that each 6th frame rendered as next frame
from report).
