Ref #14 - Added put and append button options into activity layout.  Added new AdapterBaseActivity which will eventually replace AdapterActivity. Decided it's better to offset more work to subclasses then try to make one main activity handle all possible options for each demo adapter.  XML for contains dialog is now split into two.  One for arrays and one for sparsearrays.  Added new ContainsDialogFragment for sparsearray.
Ref #14 - Fixed SparseArray adapter was not properly converting position for mutate methods. This is required for when the adapter is filtered. Fixed some package namings.
