Removed invalid code in getLanguageFileDescription,When the language is not discovered, it will use the built-in language fallback mechanism to fall back,At the same time, we also fix the issue that using language in the server does not save the settings of the server side locale

* Fix the following issues:
1. HashMap non-thread-safe issus
2. Fix the same problem in pr621, but use a better implementation

Add the following functions:
1. There is now a language cache inside getLanguage to prepare for different languages corresponding to different time zones where the accounts in the server are located

* add /language command,each account has their own Locate

fix issue 648 677

Use `LOG_LEVEL` environment variable to override logging level for `emu.grasscutter` (which also contains all loggers under it). This might help with debugging various issues reported by users. Previously, the only way to override these levels would be to use `-Dlogback.configurationFile`

i hate myself

* improve server side command line input

* prevent multiline logs from covering typed commands
