fix: config.ini

we can now do 'pecan serve ini/config.py'
the fully qualified path to config.ini must now
be set in config.py
@painterjd - I don't think that should be an issue. They are already maintaining a secondary repository and can simply have the change managed there as a single commit. Similar to how I do on our 3 webheads where each has its specific changes in a local repository on a branch (master = upstream, branch = upstream + local config changes to operate).

@powellchristoph - issues with this?
