Bargraph moves to common settings
"Global" config moves out of wtf and into cfg for the few things that need it
We can probably eliminate a global config used across things if we want to
Rather than referencing wtc.Config, instead pass the global config
Also, look up config for the module early and pass that in sooner, to deal with fewer long paths and get rid of the
ConfigKey variable
This change is largely experimental and it's entirely possible it could
wipe out your existing configuration. Be warned.
Old config path was: ~/.wtf/
New config path is: ~/.config/wtf/
If an existing config directory already exists, this change attempts to
copy it to the new location.
Note that if your config file contains paths to files in the old config
directory, they won't work. You'll need to change them by hand.
