fixed an orientation change bug

when orientation change happens, we now store the state of the selected
tab in the onSaveInstanceState method. then, when the onCreate method
fires, if there is a savedInstanceState, we use the index of the tab
that was stored in savedInstanceState.getInt("tab")
doing bulk insert now and adding waypoints
created a leaders fragment for the leaders tab on the main activity
added a waypoints class
now displaying a two item list
trying to do some bulk inserts
added two formatting functions to the walkabout class
doing some formatting to what gets displayed
set the button visibility to gone
if this comes from the main activity, we don't want to show the done button
the rest
