Feature: Allow MoveFocus to wrap

[jemag]

For example, if I am in this pane:

Wrapping would allow me to `MoveFocus "right" and still go to the pane on the left:

This is particularly useful in situations where there might be a high amount of panes such as this:

Now moving from pane#5 to pane#1 is as simple as moving the focus right.

This could be implemented in a number of ways, some possible options:

• global config option (enable wrapping globally or not)
• giving MoveFocus another parameterslike wrap
• having a completely different action MoveFocusWrapped (this is probably overkill)
