Re: [platform-ui-dev] Roles and activities

Unfortunately, the launch configuration type extension point is managed in 
Debug Core, so we can't access the Workbench when we're loading the 
extensions.

This means we'll have to do the pattern matching ourselves. However, I hit 
another problem while implementing this. The activity manager is returning an 
empty set when I asked it for the active activity ids. In the "Activity 
Configuration..." dialog, I have all activities set as active.
