Add reference images for KMonad Lite default and QWERTY layouts

I completely understand if one doesn't want to bother with all of these variations, but at least illustrations of the "lite" layout also in QWERTY variant (using KMonad) would have attracted me to the project even quicker.

Screenshots are made manually from [kle](http://www.keyboard-layout-editor.com) at 150%, because the download options are (poorly) experimental
