[dev][dwm] Patch - Keyboard layout switcher

[Andrey 'Case' Merkulov]

Hello,

this is a little patch for dwm 5.8.2.
Patch adds to dwm functionality of keyboard layout manager: for every
open window now stored current layout. If you change the focused window,
the current keyboard layout also switched.

And sorry for my english :)
