MacGui: main and queue window improvements.

Merge fPictureSizeField and fPictureCroppingField into fPictureSettingsField (fits on a single line).

Rename fVideoFiltersField to fPictureFiltersField.

Also align their contents using tabs.
This should look better overall.

Add pictureSettingsSummary and pictureFiltersSummary to generate the text summaries used in the fields above.
