Add chapter loss warning when converting to DVD format

When converting a file with chapters to DVD/MPEG format, show
a confirmation dialog warning the user that chapters will be lost.

MPEG format does not support embedded chapters - they require
full DVD authoring with IFO files. Users are warned and given
the option to cancel or continue.

Warning appears for both 'Convert Now' and 'Add to Queue' buttons.
