Feature request: configurable jump backward/forward timings in advanced settings

[jmetz4]

First off, your player is virtually perfect. It's handled everything I've thrown at it and it's certainly elegant.

For me, the only issue is that jumping back an entire minute is excessive. I jump back frequently to check SDH subs which only requires 5-10 seconds backwards at most. Would it be possible to make these timings configurable in the advanced settings menu? I'm not sure if there's a config file somewhere that I can edit but I'm on Android TV so I'm a bit limited in what I can do.
