This moves storage of balances from the baltop command into the UserMap. This was needed by Glare to able to get a hold of all users balances without causing jvm hell on the usermap.
To access this API as an end user;
```java
import net.essentialsx.api.v2.services.BalanceTop;
//...
BalanceTop api = Bukkit.getServer().getServicesManager().load(BalanceTop.class);
```
Closes#3100, closes#3540
