Timeshift keyboard shortcuts

[Dreamer]

Current shortcuts are:

PAUSE = start timeshifting
CTRL + SHIFT + LEFT = rewind (5%)
CTRL + SHIFT + RIGHT = forward (5%)
CTRL + SHIFT + UP = goto start
CTRL + SHIFT + DOWN = goto end (live)

I suggest following changes - to make it more handy and faster:

PAUSE = change the auto-zap from space to Pause

SPACE = toggle timeshift (pause/play)

CTRL + UP = forward 5 seconds
CTRL + DOWN = rewind 5 seconds
CTRL + LEFT = rewind 60 seconds
CTRL + RIGHT = forward 60 seconds
CTRL + HOME = go to start
CTRL + END = go to end (live)

CTRL + T = Toggle Timeshift (turn off/on and restart DD, if needed)

BTW - Timeshift slider and buttons (pause...) should be greyed out if timeshift is disabled, if possible.

Why? Rewind / forward (5%) can be sometimes 30 seconds, sometimes 30 minutes, it's changing all the time and user can't handle it. He don't know if 50 seconds or 50 minutes will be rewinded. Therefore i think it's not very useful.

It would be very useful also for TV window and fullscreen.
