Kxkb: Improvements for tray window pixmap manager, optimize settings reloadings

* Rename LayoutIcon to LayoutIconManager for clarity
* Remove use of singleton pattern for LayoutIconManager
* Do not reload all Kxkb settings every time we are requested to get a pixmap!
* Use pointer to global KxkbConfig instance instead of keeping own copy
* Make "Transparent background" checkbox available for theme colors in the GUI
* Minor code cleanup in LayoutIconManager
* KxkbConfig: do not reload settings every time getKxkbOptions() is called; if settings actually need to be re-read, it must be done maunally before calling this function
