FiveRP: the server from the hosting account, not the earlier one

Wrong server was published before. This is the one that runs on the
hosting account the video was made on: FiveRP - two-step registration
(account, then an identity printed onto a passport), login that returns
you to your resident, and a loading screen driven by the game's own
streaming events.

  resources/[local]/fiverp-auth          NUI + scrypt hashes + oxmysql
  resources/[local]/fiverp-characters    identity, character load, spawn
  resources/[local]/fiverp-loadscreen    loading screen
  sql/schema.sql                         accounts, characters
  docs/DESIGN.md                         the design system every screen follows
  docs/screens/                          shot from the live server

Only our own code is in here. cfx-server-data and oxmysql are fetched by
install.sh instead of being vendored, which keeps the repo at 3.7 MB.

install.sh does the whole box in one command: recommended FXServer
build, cfx-server-data, oxmysql, MariaDB with the schema, resources,
server.cfg (mode 600 - it carries the key and the database password),
boot entry, then it waits for the Cfx registration. Tested end to end on
a spare install root: 29 resources scanned, database and schema created,
and it stopped exactly where a wrong licence key should stop it.
