Allow label controls to have label2

One of the great things about button controls is you can have 2 labels, one left aligned and one right aligned, and Kodi will manage their lengths so they don't overlap. I used fake buttons in Mimic's header to achieve this same effect. This doesn't work inside container layouts, however, as buttons are not allowed in containers. It would be awesome if it was possible to give label controls a label2 and the two labels were managed like they are for buttons.

Anyone out there with the skills and desire to make this happen?
