UI Setting: Lovelace UI Startup Tab

[TASSDevon]

In the settings you can change the webui startup page, I would like to have the option to set this for the Lovelace UI rendered in Ariela as well.

Rationale is that I am making a dedicated tab with cards that are supported by Ariela because my 'default' page is getting a makeover using the button card and possibly other currently unsupported cards. Having a basic layout with supported cards in Ariela be the default page would be very handy.
