tdf#112207: Allow assigning macros to ui elements

* Adds "Macros" category to the categories list

* Search/filter feature now works also on the macros category

* Since macros category has multiple trees and subtrees, and many leaf
  elements (macros). I chose to implement the behavior like this:

  If there is no filter/search term, the trees will be presented as in the old
  macro selector dialog (collapsed), but if user types a search term, then
  filtering happens: non-matching elements and empty containers/(sub)trees
  are removed and everything is expanded so that user easily sees what
  (s)he is looking for.
