Only one progressbar in Dashboard.

I've removed @id/progress_bar from Dashboard, and for login and logout
I'm using the one from the eip fragment.
CW ProgressBar is translated below provider.

The progressbar does not show any message.

The progressbar overlaps the next provider list item. This is the next
issue to be fixed.
Added a custom adapter to the ProviderListFragment

I've created a new adapter using code from
http://www.sherif.mobi/2012/01/listview-with-ability-to-hide-rows.html
and my own getView (moved from ProviderListFragment).
Only selected provider remain visible.

The progressbar is always below the first row, because only the selected
provider row remain visible.

If the user cancels the ProviderDetailFragment, all providers appear
again.

Next step: implement the same behaviour with the new provider usecase.
New provider hides other providers.

If a new provider is added, it gets selected automatically hiding all
other providers, as if it had been selected clicking on it.
Label for the CW progressbar.
