Sub Overhaul Prototype

[sr55]

Description

New Subtitle Rules Panel (#1860)

This provides a more flexible set of options for automatically adding subtitle tracks when importing a source into HandBrake.

Would appreciate some feedback on the UX of the new panel design.

I may add wildcard support in the subtitle name field in another PR, for now I'm focusing on the core functionality .

I've dropped the Add CC when available option. it seems redundant.

Preset Format Changes:

The new preset format is as follows:

We can probably migrate the format forward to a limited degree when the mac and linux Ui's update as well.
