Corrected parameter name in GenericUdpServer constructor.
Added new action for item selection in ISelectableItemsMessenger
with error handling for missing or invalid keys.
Updated SetItems method to improve clarity and ensure proper
clearing and re-adding of item actions.
Introduces a new private field `_itemKeys` to store item keys. Adds the `SetItems` method to manage item actions and update events, ensuring proper registration and cleanup. The `SendFullStatus` method is now invoked from a dedicated event handler `LocalItem_ItemUpdated`, improving the handling of item updates.
UI Applications can now request status for specific feature sets instead of full status for a device. This will hopefully cut down on the traffic and messages required to get the data for the UI.
In order to satisfy the requirements for the `MessengerBase` class, the
`ISelectableItemsMessenger` class needs to take an `IHasInputs<T>`, as that is
the device that implements `IKeyName`. We may want to consider adding a
`IHasInputsMessenger` specifically for those devices that implement that
interface vs the `ISelectableItemsMessenger`.
In order to solve some dependency issues that keep cropping up, MC
should be moved back into the Essentials repo and loaded automatically
on startup. This will allow for all plugins that use the MC Messengers
library to use the same version without fear of overwriting a dll due to
loading of plugin libraries.
