Progress dialogs should be not cancellable outside the window

[optikalefx]

This change makes progress dialogs modal. In a sense that they can't be cancelled from an outside touch. This is expected behavior for a progress bar. Too many user errors by mis-tapping outside the progress and then having no clue what happened.

What are progress dialogs ??

I'm pretty sure that the pull request title doesn't match the description/implementation.

Sorry about the whitespace. Automatic sublime setting.

A progress dialog (notification.progressDialog is a dialog that has a 1-100 progressbar. The user should not be able to click away. You're right the title should say "not cancellable." I'll update.

[optikalefx]

The current implementation allows the progress 1-100 dialog box to be cancelled by clicking outside the dialog window. This is unexpected behavior for the user.

The issue as I meant to imply it is that only Android supports this functionality, ultimately it should be moved/removed, or implemented for more platforms.

[optikalefx]

iOS is modal by default already. So it already performs the expected behavior. I don't know about the other platforms. At least on Android this is a necessary change, and on iOS we didn't have to do anything.

Looks OK

[brody4hire]

but could be considered a breaking change.

I think we should increment the major version number before merging, will confirm in dev@cordova.apache.org before merging.

Whitespace cleanup should not be part of this change. I just raised PR #109 to cleanup the whitespace.

Closing in favor of PR #110, with whitespace cleanup done in #109. Note that PR #110 gives both reference and primary author credit to this PR.
