Merge lp:~grindhold/sakura/fading into lp:~dabisu/sakura/sakura

[grindhold]

I implemented an urxvt-like feature for focus fading.

When sakura notices that it hasn't got the window manager's input focus anymore, it will darken the foreground color. When the sakura window retrieves the focus, it will turn the foreground color bright again.

It is the last feature I am missing for sakura, as I switched from urxvt 3 days ago.
I hope to see the feature in the main branch. sakura would be the perfect terminal emulator then.

[lp:~grindhold/sakura/fading]

550. By grindhold on 2016-04-17

[David Gómez (dabisu)]

I've already merged your patch, thanks!
