-- required parameters in def:
-- name - string - potion name in code
-- optional parameters in def:
-- desc_prefix - translated string - part of visible potion name, comes before the word "Potion"
-- desc_suffix - translated string - part of visible potion name, comes after the word "Potion"
-- _tt - translated string - custom tooltip text
-- _dynamic_tt - function(level) - returns custom tooltip text dependent on potion level
-- _longdesc - translated string - text for in-game documentation
-- stack_max - int - max stack size - defaults to 1
-- image - string - name of a custom texture of the potion icon
-- color - string - colorstring for potion icon when image is not defined - defaults to #0000FF
-- groups - table - item groups definition -
--   - must contain _mcl_potion=1 for tooltip to include dynamic_tt and effects
--   - defaults to {brewitem=1, food=3, can_eat_when_full=1, _mcl_potion=1}
-- _effect_list - table - all the effects dealt by the potion in the format of tables
-- -- the name of each sub-table should be a name of a registered effect, and fields can be the following:
-- -- -- uses_level - bool - whether the level of the potion affects the level of the effect -
-- -- --   - defaults to the uses_factor field of the effect definition
-- -- -- level - int - used as the effect level if uses_level is false and for lvl1 potions - defaults to 1
-- -- -- level_scaling - int - used as the number of effect levels added per potion level - defaults to 1 -
-- -- --   - this has no effect if uses_level is false
-- -- -- dur - float - duration of the effect in seconds - defaults to mcl_potions.DURATION
-- -- -- dur_variable - bool - whether variants of the potion should have the length of this effect changed -
-- -- --   - defaults to true
-- -- --   - if at least one effect has this set to true, the potion has a "plus" variant
-- uses_level - bool - whether the potion should come at different levels -

-- drinkable - bool - defaults to true
-- has_splash - bool - defaults to true
-- has_lingering - bool - defaults to true
-- has_arrow - bool - defaults to false
-- has_potent - bool - whether there is a potent (e.g. II) variant - defaults to the value of uses_level
-- default_potent_level - int - effect level used for the potent variant - defaults to 2
-- custom_on_use - function(user, level) - called when the potion is drunk
-- custom_effect - function(object, level) - called when the potion effects are applied
-- custom_splash_effect - function(pos, level) - called when the splash potion explodes
