Language identifiers are stored and retrieved, rather than English
names.
Language weighting biases towards the current language, rather than to
English.
Language is no longer considered nullable to indicate English.
Duplicate names in other languages are no longer omitted from the index.
Previously, every single spline-pokedex request tacked another markdown
extension onto a global list in spline, making markdown processing just
a little bit slower over time. This is terrible.
Now we do something a little less crazy and a little more global. Wait,
is that less crazy or more?
All accessors now take a `root` arg, the root of the media tree.
Alternatively `root` can be a custom MediaFile subclass, which should allow
neat tricks like:
- Checking some kind of manifest to prevent stat() calls
- Custom properties of the file objects (e.g. for HTML <img> tags)
- Downloading the media on demand
Tests assume media is at pokedex/data/media, skip otherwise.
- the Session has a `pokedex_link_maker` property, whose `object_url`
method is used to make URLs in Markdown
- pokemon.names_table.name is now an ordinary Unicode column
- pokemon.name is a MarkdownString that is aware of the session and the
language the string is in
- pokemon.name_map is a dict-like association_proxy of the above
- move.effect works similarly, with transparent $effect_chance substitution
as before
- as_text() is now a function that takes the session as an argument
- likewise as_html(), which also takes URL makers and the language
- since there should be only one link extension, it is registered by
setting default_link_extension, not appending to markdown_extensions.
This only affects the __html__ attribute.
Sometimes, translations are incomplete. Handle this gracefully by allowing
fallback languages. If there are none, fall back to the identifier to get
at least some order.
