Remove hardcoded URLs in favor of Config.routes

[scheibo]

As discussed previously, the primary motivation here is to be able to host a staging/testing environment for Pokemon Showdown's current set up. Supporting arbitrary client configurations and truly generic hosting setups is a non-goal. Starting with the server side changes here because the client changes are more involved.

Specific replays which wouldnt exist on another server

server/chat.js:const LINK_WHITELIST = ['*.pokemonshowdown.com', 'psim.us', 'smogtours.psim.us', '*.smogon.com', '*.pastebin.com', '*.hastebin.com'];
server/chat.js:			'pokemonshowdown.com': 1,

Whitelisting

server/ladders-remote.ts:		return [`<tr><td><strong>Please use the official client at play.pokemonshowdown.com</strong></td></tr>`];

Only 'play.pokemonshowdown.com' is official, so this is still correct

server/static/404.html:<p>This is a <a href="http://www.pokemonshowdown.com/">Pok&eacute;mon Showdown</a> server.</p>
server/static/index.html:<p>This is a <a href="http://www.pokemonshowdown.com">Pok&eacute;mon Showdown</a> server!</p>

PITA to change without introducing a build for these files to replay the constants. Will need to do that on the client, but seems like overkill here. Also contains a reference to psim.us, once again, not sure worth what it would take to generalize

test/server/chat.js:			`<a href="//dex.pokemonshowdown.com/pokemon/oshawott" target="_blank"><psicon pokemon="Oshawott"/></a> &gt;w&lt;`

Should probably also not be hardcoded, but translations are half baked anyway

Looks good. One day, though, we should strongly type the Config object exported from config-loader.

Maybe it should extract the type exported from config-example.

There's a pending review request from Hoeen so I guess I'll leave this unmerged for now?

[scheibo]

The pending review request is automatic due to CODEOWNERS, but I dont think this is a change Hoeen would care about...
