Add enableBackdropDismiss to LoadingController

[imgx64]

This is a feature request for Ionic 2. I would like to have enableBackdropDismiss in LoadingController, similar to the same feature in AlertController.

My use case is cancellation. Let's say the user started a long-running task (such as uploading a file) and the app showed a loading dialog. The user should be able to tap outside the loading dialog to cancel the upload. I can handle the cancellation from the code, but the LoadingController blocks all user interaction.

Another approach for this use case is to add a way to put a spinner inside an Alert dialog. For example, a content property which can be set to arbitrary HTML (<ion-spinner>, etc.).

Hi, is there is a way to prevent alert dismiss when pressing back-button with enableBackdropDismiss = false; ? @jgw96

Hello all! While this is an awesome feature request it is not something that we plan on doing anytime soon. Because of this I am going to move this to our internal feature tracking repo for now as it is just "collecting dust" here. Once we decide to implement this I will move it back. Thanks everyone for using Ionic!
