include module exports in instructions

[grenade]

in issues #2493 and #2576, users saw an error (TypeError: Cannot read property 'timeout' of undefined) that is not easy to understand because they had edited their uiconfig files according to the instructions here, which omit the export. This change is to include an example of a complete uiconfig file to reduce confusion by users who copy and paste the example code over the entire contents of their existing uiconfig.

• What is the new behavior (if this is a feature change)?
