Document the commonConfig.js parameter 'queryForOrg'

[bsnider]

Please add a comment to the commonConfig.js and the readme.md files explaining the purpose of the queryForOrg parameter. Many users do not know that changing the value to false allows the app to use non-ArcGIS Online services.

We can add a comment to the code, but we also have a brief discussion of that parameter found in the Configure utility services wiki under the Configuring within the application section.

Thanks for showing me that!

@bsnider are you up for submitting a pull request which adds a comment (probably best to include link to the doc @iwittenmyer mentioned)?

if so, let me know if you need help.
