Icons for "local variables" and "parameters" are same as "fields" in completion data lists

This used to look okay before MonoDevelop 4.0/Xamarin Studio when they were blue blob things, but now they are all capital letter "F"s. We need different icons for locals and params in completion data lists.

So, it turns out that the C# icons are the same. They probably shouldn't be F's but it means there is no other appropriate stock icon we can use right now.

If anyone wants to play around and see if any other existing stock icon is a better fit, see here: https://github.com/ramon-rocha/MonoDevelop.CobraBinding/blob/master/CobraBinding/Completion/Icons.cobra#L31
