0.6.0

• NEW: Added new artifact 'helper'. This artifact includes several util and databinding related classes to help you to improve your app quality. Take a look inside the related folder to get an idea (https://github.com/Mordag/archtree/tree/master/helper/src/main/java/archtree/helper)
• NEW: Added new artifact 'list'. This artifact can be used to create databindable list and connect those with your viewmodels using the given ObservableList. To bind your item source to a certain list view, you can use the attribute "archtree_itemSource". The item layout can be set using the attribute "archtree_itemLayout". There are two support list types inside this artifact: BindableLinearLayout and BindableRecyclerViewLayout
• NEW: Added several new builder methods for the toolbar, ui visibility, menu and databinding component.
• NEW: The BaseViewModel got some new additions as well. You can now override the onBackPressed and onOptionsItemSelected inside this class. Those methods will be called from the underlying Android native implementation. That should help you to reduce your code from the activity classes.
• BUGFIX: Added missing getView to the ArchTreeFragment class (5d2904f)
• BUGFIX: Fixed the visibility of serveral methods.
• BREAKING CHANGES: All databinding related attributes has been changed their name to "archtree_(oldName)" to prevent name clashing with other libraries. (05ce221)
