Pass modifiers when clicking unfocused windows.

[Vladimir-csp]

Describe the bug Seems to be related to #891. And it works in sway.

To Reproduce

• open two terminal emulator windows (I use sakura)
• run mcedit in window 1
• focus window 2 and select some text in it
• shift+middleclick in window 1 (unfocused, mcedit requires holding shift to paste text on middle click)

Expected behavior Selected text is pasted into mcedit.

Actual behavior Nothing happens.

Wayfire version wayfire/testing,unstable,now 0.7.4-2 amd64 (Debian package)

I am pretty sure that this works in Sway because it has focus-follow-mouse. In wayland, a window which does not have keyboard focus does not have any access to the keyboard modifiers, so thus the terminal doesn't see that you have shift pressed.

I have focus-follow-mouse disabled in sway, it still works.

Ok, that's weird. I'll have to look at it again then.
