RFC: Remove native dialog

[NiklasMerz]

Request for comments: Remove social share dialog
I found a way to do that, but I think this sould be configurable.

@j3k0 What do you think about a mode for this plugin, which removes the native dialog.

[j3k0]

Sure, good idea. Sorry I've been very busy lately, I'll review the PRs.

[j3k0]

If I understand correctly, this PR completely removes the native dialog.

I wonder about Apple's reaction to that. Well, the plugin already is borderline, but I remember having read that ShareExtension should do their job before switching to the app.

Anyway, I guess it should be an interesting option. Default true when the type identifier isn't public.image, false otherwise, probably.

@j3k0 Thanks for all reviews.

Good point. The final PR should at least have an option to enable the dialog if the developer wants to do that.

I will try to do that when I find time. For now this PR removes the dialog completely if anybody needs this.

@NiklasMerz Welcome. I published version 1.2.0 with the 3 PRs merged today. I didn't really test much, so I trust you guys that it's stable enough!
