content: sprawl & transformContent

Sprawling basically means tying a component to objects which
aren't directly passed to it. This is necessary for functions
like transformContent, which was *mostly* implemented here
(the multiline/lyrics modes are stubs, and a number of links
haven't been implemented yet).
