1466: Add colors for authed players. Deprecates #1299 r=def- a=Learath2
Not sure if a snap item is the best idea for this but it should help with not sending the data more then needed and keeping it properly updated. The colors aren't great now but we can fix that easily.

SHA256 was chosen because it is reasonably standard, the file names
don't explode in length (this rules out SHA512) and it is supported by
basically all versions of OpenSSL (this rules out SHA512/256 and SHA3).
The protocol is changed in a backward compatible way: The supporting
server sends the SHA256 corresponding to the map in the `MAP_DETAILS`
message prior to sending the `MAP_CHANGE` message. The client saves the
SHA256 obtained from the `MAP_DETAILS` message until the next
`MAP_CHANGE` message.
For servers not supporting this protocol, the client falls back to
simply opening maps like in the previous scheme.
Remove the `map_version` tool, it is not being used and would have been
a little bit effort to update.
Use the OpenSSL implementation of SHA256 if it is supported, otherwise
fall back to a public domain one.
Fix#1127.
This is done by HTTP POSTing to a location specified by
`sv_modhelp_url`. We also provide a `src/modhelp/server.py` which can
use theses POSTs to forward them to Discord servers.
The POST contains a JSON object payload, with the keys `"port"` which
contains the server port, `"player_id"` which contains the calling
player's client ID, `"player_name"` which contains the calling player's
nick and `"message"` which is the user-specified message.
Make JSON-escaping function public, add tests and fix bugs uncovered by
these tests.
Supersedes #1129.
