Karl Blomster ffa5a2021d - Reworked the SMPTE timecode handling with Plorkyeran's help. It does now handle dropframe timecodes as well; the ms->SMPTE handling has been tested and seems reasonably correct, while the reverse conversion remains untested and unused. The Adobe Encore export filter will now use dropframe timecodes properly (previously it would play pretend with wallclock hours/minutes/seconds and incorrect frame numbers).
- Changed the SubtitleFormat::AskForFPS dialog box; removed the "PAL/NTSC only" choice and added a "show SMPTE dropframe" parameter instead. Also added 50fps as a choice.

- While I was at it, reworked the TranStation export filter so it actually looks ahead to see if the next line will overlap with the current, and if so, move the end time of the current line backwards one frame, which fixes #767

Originally committed to SVN as r2920.
