This makes gen 7 the default mod, updates the tests to match, and fixes
the corresponding build error.
Note that this only changes the default Tools mod, the default Formats
mod is now gen6. gen7 must be specified by name in a format, for that
format to be a gen 7 format.
Battle is now an ES6 class... mostly... it's complicated.
Battle's inheritance system has always been a mess. I tried to redo it
in a sensible way but it caused nondeterministic test failures. Not
even kidding; different things would fail each time I ran tests, even
without code changes. I'll investigate closer later, but this refactor
makes it use ES6 classes with only a small amount of hacking, which is
good enough. It is, at the very least, simpler than the previous mess.
BattleEngine.Battle.construct has been renamed BattleEngine.construct.
Tools will be renamed to Dex soon, which is why the code inside Tools
is calling itself "Dex" now, but right now we're just refactoring its
internal code and not officially renaming it yet.
In the meantime, Tools is now an ES6 Class.
A long-standing bug in learnset loading order (the one
test/chat-plugins/datasearch.js tests for) has finally been fixed, so
Tools.includeMods() is no longer necessary to accurately access modded
data.
Tools.mod has been split into Tools.mod(modid) and
Tools.format(format). The issue of Tools.mod being ambiguous about
whether it's passed a mod or a format hasn't been a _bug_ for a while,
but this is still more readable.
Other renames include:
Tools#isLoaded -> Tools#dataLoaded
Tools.includeMods() -> Tools.includeModData()
Tools.preloadMods() -> Tools.includeMods()
Tools.preloadedMods -> Tools.modsLoaded
Tools.moddedTools -> Tools.dexes
Do not just rename your calls of Tools.includeMods() to
Tools.includeModData(). With the learnset loading bug fixed, there's
no reason to use it unless you need direct access to
Tools.dexes[...].data for some reason (you don't, just use
Tools.mod(...).data)
