Add the Programming Layout option

Browse Source 
Allow specifying a layout for programming and add a key for switching to
it easily.

The switching key is placed on the top edge of the space bar.

The option has no effect by default because the ergonomic isn't ideal,
it needs to be enabled explicitly.
Users of Latin-script languages certainly prefer to use one layout (for
programming or not). This feature might be removed in favor of a better
language-switching mechanisms in the future.
