For a long time, connecting to non-localhost servers didn't work without
an HTTPS cert. But it's now once again possible. All you need is an
IP with an open port, and a dream.
Syntax is a little different than before. To go to `1.2.3.4` at port `5000`
- before: `http://1.2.3.4-5000.psim.us`
- after: `http://1-2-3-4--5000.insecure.psim.us`
Supporting multiple dots in the URL is too complicated, unfortunately.
The other way still works: `http://1.2.3.4:5000`
And yes, I would 100% recommend that one.
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.
