Jan Henning 222df1171c Bug 1270543 - Part 1: Enable double tapping to select an action in the prompt dialog. r=liuche
On newer Android versions, double tapping an entry in the app chooser is equivalent to tapping it once and selecting "Just once". To enable this functionality for our own app chooser when downloading a file, this patch enables passing a button index to the prompt dialog which will be chosen by default if a double tap has been detected.

To do this, we track the input value we receive in onChange. If we receive the same value twice in a row and a button has been configured, we close the dialogue and pass the result with that button back to the caller.
