Mpris + obs-tuna fixes

[Araxeus]

I've been testing on discord with @JoeJoeTV (many thanks for all the hours invested 😃 ) and we managed to fix all mpris issues (play/pause not working + update progress attribute + seek from mpris + seek to mpris)
should close #372

original comment with mpris bugs: #65 (comment)

docs:
https://www.npmjs.com/package/mpris-service
https://github.com/dbusjs/mpris-service/blob/master/src/index.js#L26-L132

For obs-tuna this implements a live update to the progress

also fix #487 by changing status from Playing/Paused to playing/stopped

this pr also adds a songInfo.album for both mpris and tuna (when available, never is available if current song has a video)

ps. mpris could maybe be moved to its own plugin instead of 'camping' inside the shortcuts plugin
