The Grocy enabled feature flags can be set with either a bool or int value (ints are passed by the Grocy API as str). The HA Grocy addon uses an int, the Grocy config.php suggests a bool. Now both are correctly interpreted.
A disabled Grocy feature no longer floods the log if the related entity is disabled.
If a "disabled feature while the entity is enabled" situation occurs, it will only be logged in debug.
Fixes #203
