Feature: Allow device name to be customized

For users with multiple devices, like 3 mixers for hcs and dhw name and type are not clear. Maybe think about custom device names, or add, depending on device-id, the circuit to the name (e.g. "MM100 (hc1)"). But i think optional custom names are better.

This feature is to extend the Settings->Customization page to allow the EMS Device Name to be renamed. I suggest adding a RENAME button to that page after a device is selected. And the name will be stored in the customizations masked_entities alongside the product_id and device_id which makes it easier and less code. If the custom name is empty ('') it will default to the one stored in Flash from device_library.

It sounds simple but there is some backend code to write.

As our DB is growing and we're seeing multiple brands and models using the same ProductID I think this is important to add as a next feature. I'll add a Rename option to the Customizations WebUI.
