Allow more than one Salesforce instance to connect to AHA

Usually before you roll out big changes to any Salesforce instance you test this in a Sandbox. We would however like the Salesforce Sandbox connection with AHA to continue to function to further test profile changes and their impact on the AHA connection. Plus the Sandbox idea portal now holds a bunch of bogus test ideas you don't want to expose to Production users.

So what we want is the ability to setup more than one idea portal which is possible today but connect each of these with a separate Salesforce instance.
