    Editor / Improve keyword selection (#1129)

    Instead of selecting keywords in a popup, select them directly in a thesaurus widget in the editor. Improvements:

    support to easily add keyword to a previously selected thesaurus
    support CharacterString, Anchor and XLink mode (and change the mode at any time)
    keep default editing mode for free text keyword editing.
