[Podfile Editor] Allow option clicking on a pod

[pedrovieira]

This PR implements #302 - "Allow option clicking on a pod":

• Option click/three finger tap on a pod name to show the popover with the cocoapods pod page
• Hovering the pod name with the option key down will also underline the pod's name
• Clicking on any link inside the popover's WebView will redirect the user to the browser
• Custom CSS to remove cocoapods.org global menu from the popover's WebView

How it looks:

Would love to get some feedback.

Is there a way we can do this without associated objects? Not sure for OS X, but they're a pretty bad idea to rely on in iOS.

What if we subclassed or extended SMLTextView to add the functionality we need for this?

[pedrovieira]

@nwest What I'm currently doing is extending the SMLTextView for the option-click functionality. I can change this to be a subclass of SMLTextView but we also need to subclass MGSFragariaView since the textView property is read-only. This doesn't mean it's hard, I'm just putting all on the table.
This solution was primarily chosen because it needed less components to be changed in order to work.
What are your thoughts on this?

nice touch with forPodAtRange

Alright, yeah, I'm happy with that explanation - I should fix the danger CI issue - but that's not a blocker here 👍

[orta]

Ah, it has merge conflicts - good to go after that's handled
