Request: Add optional indicator for parameters on calltips

[GroggyOtter]

Can you please change the display behavior for optional parameters in the calltip?
Items marked as optional in their JSDoc tag should display as optional in the calltip:

This is how it's marked in the definition: @param {(String)} [Text]

This is how the calltip looks:

This is how I think it should look:
Adding brackets around the parameter would indicate the parameter is optional, as sometimes it's not apparent in the code line up top.
