remove alias water_lily -> lily_pad
create alias water_lily_flower -> water_lily
remove alias water_lily_flower -> water_lily

We don't usually end flower tags with *_flower.
(had to repeat the first BUR or else it won't let me submit this)

This risks creating ambiguity, because of the predominance of water lily pads in artwork, even more than the flowers themselves (which is the whole reason why it was aliased in the first point). Let's just have an utility alias so both tags can be found easily.
