Document that flow and mortar (will be) used
1st step with mortar
group mortar/flow test files
Update docs
FIX: TaskManagingApplication::loadTask was not running in a transaction
Switch to Flow/Mortar.

- Release build not working yet
- Crouton not implemented yet
Enable croutons via posting to the eventbus
React to TaskRenamedEvents and show aCrouton
Remove unneeded dependency to event bus
dagger: refactor modules bc. AndroidEventPublisher gets a different bus than e.g. BaseActivity. Still an open issue.
Including the EventBusModule twice (in BaseActivityModule & AndroidApplicationModule) creates TWO scopes for singletons. Observed effect: Events published from the backend (AndroidEventPublisher) were not visible in the fronted because they used different EventBus instances.
Switch from Fragments to Flow/Mortar because it is easier to test & write.

Tablet not supported yet.
