Launcher: mod profiles, sharing them by code or file, and Thunderstore dependencies

The Mods page has a third tab, PROFILES. A profile is a saved list of which
mods are on, in what order and at what version; every mod stays installed
once, in the one Mods folder. Loading a profile rewrites mods.json, switches
off what it does not name, and downloads from Thunderstore what it names
that is missing. Profiles live in Mods/profiles.json.

A profile travels the way r2modman's do, so the two managers read each
other's: export.r2x inside a .r2z file, and a code on Thunderstore's
profile service. Config files in an r2modman profile are ignored.

Installing or updating a Thunderstore package now brings the packages it
depends on, needed ones first, leaving out any already installed at a new
enough version. A mod pack is a package that is nothing else.

A kick, by an admin or by a passed vote, used to keep the player out until
the server restarted. "kick_minutes" in the players section of the config
(1-1440; 0, the default, is still until the restart) and the console
command "kick-time <minutes>|restart" now set how long it lasts.

The player is told how long when they are kicked, and how many minutes are
left if they try to join early. A kick keeps the time it was given, so
changing the setting is for later kicks. Bans are unchanged.
