The subtitles duration factor change on the SyncControls widget constructor caused the subsdelay filter to be activated when the synchronization dialog was first opened.

- Subtitles duration update was moved to the update function (which turns b_userAction off before updating)
- updateSubsDuration was renamed to initSubsDuration
