Make `g t` shortcut contextual

[4www]

Ref: #213

The shortcut used to "go to tracks", g t, should go to the current channel loaded on the route's tracks.

Right now it is going to the logged-in user channel's tracks page.

Maybe if the current route is not a channel route it should go to the tracks route of either:

• the current channel being played (i'd say so)
• the logged in user

So then:

• if the user would like to go their tracks page, g i + g t would work
• in case the user wants to go to the current channel tracks g c + g t would bring them there

Sounds good.

So when you press gt we find the channel from here, in priority?

1. use channel route (or any child route of that)
2. use player.currentChannel
3. use session.currentUser channel
