`import =` and `export =` are really only intended for backwards
compatibility with CommonJS. While I really don't like the new module
system TC39 has designed for us, it's what we should be using, and
consistency is important.
This is mostly a TypeScript refactor, but it does come with several
renames:
Dnsbl -> IPTools
Dnsbl.query -> IPTools.queryDnsbl
Dnsbl.reverse -> IPTools.getHost
Hotpatching and running `./pokemon-showdown` now automatically run
`./build`. There should now mostly not be any reason you'd want to
manually run `./build`, except if you're invoking tests directly.
In addition, a lot of redundant code has been removed.
I'm not 100% sure this works on Windows, but I'm sure I'll get reports
if anything breaks.
Also move mods/ to data/mods/
This makes PS more monorepo-like. The intent is to further separate
the sim and the server code, but without fully committing to splitting
the repository itself.
We now support `./pokemon-showdown start` in addition to
`./pokemon-showdown`. I'm not clear which I want to be the default
yet.
