Add additional parameters to XExtensionItemSourceApplication

[irace]

Talk with @chrismaddern to make sure we’re on the same page with regards to which parameters apps should use to attribute themselves.

Here’s what we have so far: https://github.com/tumblr/XExtensionItem/blob/master/XExtensionItem/XExtensionItemSourceApplication.h

It looks as though the Button Deep Link Interoperability RFC only includes the following:

• Store ID
• App name
• Display title

The first two are already included in XExtensionItemSourceApplication and display title doesn’t really make sense in the context of share extensions, so maybe we don’t have too much to discuss after all?

After some internal discussion it seems like it’s worth adding the following optional properties as well:

• Google Play ID
• Web URL
• iOS app URL
• Android app URL

One could envision a scenario in which an app, e.g. Instapaper, shares into a service like Tumblr and we want to be able to give users who view the post the option to either install the app if they don't already have it, or deep-link in if they do.

Can’t the iOS App URL be derived from the app ID?

Can’t the iOS App URL be derived from the app ID?

This would be an app URL like instapaper://x-callback-url?article=12345

Ah, okay. Got it.
