Archarodim:
    - Only trigger a "friendly healer under attack" alert if the damage is higher than the 'heal threshold'
    - - Add configuration controls to manage existing 'name to custom marks associations' (view, change, clear) - Fixes and improvement to custom marker UI.
    - Added /hhtd ShowGUI command (in addition to the existing /hhtdg)
    Just so that it appears when typing /hhtd because otherwise people may think there is none... (unless they read the doc)
    - New module: CustomMarks - Allow users to set persistent custom marks on targets (only seen by the user) - (type /HHTDG)
    - Move HHTD healer marker texture reference to a more specific sub-table (plate.HHTD.NPH
    - Add an option to swap friends and foes symbols
