Add ability to save and restore Synchronised Clip Custom Settings

[latenitefilms]

This was basically what @randomeizer started off doing prior to going down a cp.ui rabbit-hole in #3000.

I think the best/easiest way to do things is probably to make a user interface that basically looks identical to the Synchronised Clips user interface, but add the ability to save custom settings. We could then have actions that trigger the "Synchronise Clips" menu bar item, then automagically change all the settings as per the saved preset.

This might already be solved in #3000, but I assume most of the popup menu bar values are stored in a .nib somewhere.

We could even do something crazy, and use a watcher to detect when the "Synchronise Clips" sheet is visible, then "draw" an interface on top, for saving/restoring presets in a similar fashion to how we currently do Overlays.

Great, I would following options, if possible:

• choose Spatial Conform of Source Video (Fit, Fill, None)
• Format always on custom to quickly type in Resolution
• set TC to Start-TC of Source Video
• choose naming between Name of Source Video or Source Audio
• choose Spatial Conform of Synced Clip

would it be possible to "Sync without Audio" or place a dummy Audio Clip with no content?
