Delete tasks
Switch to an event bus for domain events.
Fix: TODO Contentprovider now returns 'success' on create
Allow for updates in the dependencies.
Enable proguard. Untested, bc. the release build is not yet signed
Add release-signing.
Make code with findbugs annotations survive proguard.
Retain the detail fragment across configuration changes (rotation).

Fixes the following bug: After rotating the screen, the fragment in the listactivity was null. This resulted in an NPE in the android stack bc. the TodoDeleted event handler passed null to the fragment transaction.
Fixed racing condition between loading data and saving in onStop()

The racing condition allowed task to be set to "all blank" values.
When the user switched to a different task, and the detail view was not loaded yet, the task was updated with the "unbound" fields.
Fix: A deleted task should not be saved onStop.
Hook the list fragment into the event bus.

Open issue: the Crouton shown in the TodoDeletedEvent handler is not shown (or only for fractions of a second)
Class actually not used.
Remove idea project file

android sdk installer requires expect to be installed.

Error was: '/dev/stdin: /home/travis/.android-sdk-installer/tools/accept-licenses: /usr/bin/expect: bad interpreter: No such file or directory'
