-- Changelog:
-- 02.09.2021 * Added a history of stored patterns (not saved over server restart)
-- * Added a menu to select a history entry. It is accessable via AUX1 + left click.
-- * Removed deprecated functions get/set_metadata(..) and renamed metadata to pattern
-- 29.09.2021 * AUX1 key works now same as SNEAK key for storing new pattern (=easier when flying)
-- * The description of the tool now shows which pattern is stored
-- * The description of the stored pattern is more human readable
