Add cue at current time for subtitles

[Arnei]

Adds a hotkey (Shift+Alt+e) to the subtitle editor. It allows the user to add a new subtitle segment, based on the current time of the video.

Resolves #1313.

Thanks for that. There is one small issue, every time I use a keyboard shortcut to add a subtitle segment, the special character corresponding to the shortcut is added to the new segment. I would expect it to just add a new empty segment.

This is not only true for Shift+Alt+e but also for Shift+Alt+q and Shift+Alt+a.

@snoesberger I could not reproduce it. Is it still an issue for you?

Yes, it is still a problem, I just tried again. It depends on the keyboard language you are using. If you're using a standard German keyboard layout (de), you won't see the problem. With a Swiss-German (de-ch) or US layout I'm able to reproduce the problem in different browsers.
