Fix database memory leaks.
Implemented Caching of PlayerAccount.
Economy now is cached, in semihybrid mode, this mean if player is online is used cache but if is offline is used database.
Cache is synchronized with database when player joining server and if leave server or in shutdown process cache is flushed to database.
Added new command eco debug, this command will be in future with more functions.
LiteEcoEconomyAPI was changed to caching.
EconomyPlaceholderAPI annotated like a deprecated will be in future moved into expansion to ecloud.
Small fixing of typos and missing translations.
Probably improvement function what want LcyDev with purgeInvalidAccounts()
and other stuff.
