make the list of channels collapsable

[sdcosta]

There should be a small x button somewhere to make the list of channels collapsable.

Compelling use case:

On lower resolutions it takes up alot of space (about 50% of the width), and having it collapsable would allow the items to be read more easily.

Marco already has some code for this, which I put in the lilina theme. I guess he will release it soon. For now, one can use the lilina theme.
