Rest.cs got a lot of commenting at last.
Redirects and upgrades can now be easily added for REST routes via the `Rest.RegisterRedirect(base, target, upgrade)` method.
Redirects added for all routes. Upgrades added for `/world/bloodmoon` and `/v2/world/autosave`, as they both use old-style REST verbs.
Added token bucket and timer to degrade token bucket
Modified REST API rate limiting
Changed limiting to only be on token create and v2 token create
Added config options to choose time limits
Passed HttpContext to the execute method of endpoints
Made blocking failed API logins optional
Changed error codes on failed login to be ambiguous
Added config to decide whether all or failed logins are limited
Changed config variable names
Cleaned up duplicate code in REST rate limiting
Fixed my typo
Changed error 431 to 403
-Added REST endpoint "/v2/server/restart".
-Added REST endpoint "/v2/server/reload".
-Added REST endpoint "/v3/server/rawcmd", will output all returned lines as an array instead.
