* Official implementation of Meteor Storm behavior
-- It deploys all units directly at castend
-- Each unit has a different expiration time
-- On the last interval of a unit the meteor will appear
-- When the unit expires, it will deal damage
-- If the unit gets removed at any time, no meteor will appear and no damage will be dealt
* It is now easily possible to configure Meteor Storm behavior via database files, no more extra coding required
* Fixed Meteor Storm sometimes dealing damage even though no meteor appeared
* Fixed Meteor Storm being able to hit through walls when the caster has moved in the meantime
* Catnip Meteor will now create 3-7 meteors depending on level
* Catnip Meteor now has an interval of 500ms instead of 1000ms
* Catnip Meteor now has a curse duration of 20s instead of 5s
