keyboard-shortcuts-inhibit: Add client example
Again, copy'n'search'n'replace the idle inhibit example to become a simple keyboard shortcuts inhibit example, adding the active and inactive events. Getting the initial inhibitor needs to be done later than for idle inhibit to avoid an error "xdg_surface has never been configured". Signed-off-by: Michael Weiser <michael.weiser@gmx.de>

+/**
+ * Usage: keyboard-shortcuts-inhibit
+ * Creates a xdg-toplevel using the keyboard-shortcuts-inhibit protocol.
+ * It will be solid green, when it has an keyboard shortcuts inhibitor, and
+ * solid yellow if it does not.
+ * Left click with a pointer will toggle this state. (Touch is not supported
+ * for now).
+ * The compositor (de-)activating the inhibitor will also toggle state.
+ * With a compositor supporting the protocol, compositor shortcuts will be
+ * suspended while the inhibitor is active and the window has focus.
