As a user I want to be prompted to confirm my cancellation of an app install, so I do not accidentally cancel the installation of an app that I actually do want.
This is requirement AppInstall-003 https://docs.google.com/a/tola.me.uk/spreadsheet/ccc?key=0AtuYwL8qXqZmdGQtNHJ6S2NxZXlmYVctRS1xbEh3V0E#gid=73
Remaining required feature work listed at http://j.mp/VWpueM is now blocking+ to ensure visibility and tracking, per drivers' decision.
We're marking this bug with the C1 milestone since it follows the criteria of "unfinished feature work" (see https://etherpad.mozilla.org/b2g-convergence-schedule). If this work is not finished by Nov19, this bug will need an exception and will be called out at the upcoming Exec Review.
