tdf#91874 Command Popup - HUD to search and run LO commands

This adds Command Popup functionality, which is a HUD like pop-up
window, which can be used to search and run commands presented in
the main menu (but not limited to that only).
This is the initial version, which has limitation in searching
and running the command (doesn't work for some currently).
