This syncs data/text to exactly match the client's data/text, in
preparation for them to be merged. The server's data/text will be
canonical, moving forward:
Relevant changes:
- A new file `data/text/default` has been added, for battle messages
not associated with a move/item/ability.
- As One (Glastrier) and As One (Spectrier) should not have a start
message; only As One itself.
- Hidden Power's `realMove` property does not belong in data/text
and has been removed (it's still in data/moves where it belongs).
This adds some new `data/text/` files, which are the new home for
item/move/ability descriptions, as well as in-game messages, in one
place for ease of translation.
