batctl manpage adjustments

batctl: adjust "-w" option, vis options and minor layout things

This patch adds documentation for the new way of enabling/disabling
and handling the vis server. It also adds documentation for the change
from "-b" to "-w" in the according options. Furthermore, the sub-option
alignment has been altered in some places.
