Allow mockup field settings in ctools_field_invoke_field()

OG is also going to use it, see screenshot of sub-widgets in #1730678: Provide a "complex" widget instead of "Primary" and "Secondary" fields.

This patch only populates $field if $field_name is an array.

The reasons are:

1. I didn't want to change the function signature
2. Assuming you need a mocked field, then anyway you'll need to load it and add your own settings

What other solution do you prefer?

That seems like it could lead to errors in other use cases.

All i know is that atleast my current use case(s) for OG and OG-vocab, which creates "sub-widgets" is actually working really nicely thanks to how cool CTools and Field API are :)

This patch only populates $field if $field_name is an array.

Re-read, and you are of course correct, ignore #3, patch coming soon :)

Hi guys, OG vocab 7.x-1.x is now using it as-well. Any chance getting this in soon, so testbot won't fail all my tests?

How many mistakes can I make in 3 line patch :/

Gentle bump :)
