Added the ability to create and delete lists, rename is next.

@edfloreshz Do you plan to use these segmented blocks like in COSMIC settings for your list elements?

@mr_esn They are being used in the details pane

@edfloreshz Do you plan to use them in main interface? I think it will look better with them

@mr_esn I can set a similar style to the task list but using the same widget would not be convenient.

@mr_esn How's this?

@edfloreshz Much better
