Subject: Make bar widths configurable

Previously, each module defined its own width for the bar (typically 12
wide), should the output be bar format.

This introduces a config_node level configuration "width". This
configuration is ignored unless display == bar in the config for the
given module. This width configurations allows the width of each module
bar to be configured by the user without requiring modification of
source and recompiling of the app.
