Clicking on deck controls affects library keyboard focus

[Ilkka Tuohela]

After clicking on controls in deck panels, keyboard shortcuts for library view browsing stop working until you click in library with mouse.

Steps to reproduce:
- Browse a track from library with arrow key shortcuts
- Load track to deck and let it play for a while if you wish
- Press 'eject' in deck view to unload track from deck view

Expected behavior:
- Arrow keys still work to select tracks in library view as usual

Observed result:
- Arrow keys stop working
- Keyboard shortcuts related to track work ('load to deck')

Note (ronso0)
I consider this fixed almost entirely:
No pushbuttons, sliders, knobs or the deck overview accept click focus anymore; even after opening the cover art or hotcue context menu the focus is returned to the previously focused library widget.
It's only the scrolling waveforms that still accept click focus.

Thank you for the bug report.
I can confirm this with 1.12.0-alpha-pre (build master r3499+) on Ubuntu Precise.

this bug i tracked but another thing has pooped up. even when i pause a song in deck library table freezes and i can't browse using arrow keys immediatly but after using mouse it's okay agian....
is this a expected behavior or a bug?

i guess it's about focus. tab focus is lost from library table and it doesn't come back.

There are multiple components in the deck view, where clicking on it 'steals' the keyboard input focus from library view.

I'm not sure if we can fix this in one place ('all components in deck view should return keyboard focus to library') or is the fixed in many places independently.
