Multi-device support

[mhantsch]

This is likely a very low-priority issue.

If a user connects multiple UHKs to one PC, how can they select which keyboard they want to configure in Agent? What if they want to update the firmware of one particular keyboard?

Easy workaround is of course to only plug in one UHK at a time.

This is totally planned. Now, we also have an issue for it. :)

When there are more than one UHKs connected, display the following sticky device tabs:

• Make the side menu show the selected device's settings.
• When hovering over the device edit (pen) icon, display the "Edit device name" tooltip and make the current device name editable.
• When more than 2 devices are connected, show a downward-pointing arrow on the right side of the sticky device tabs and make it display a menu of the additional device names. When selecting a device from the menu, replace the current device tab with it.
