Search for favorites functionality and splash fix

On the splash screen, the attempted login is using the stored remember
token and not the user email and password. Search for favorites will
grab the first page of elements and display them.
Search for favorites page ability in adapter

In the search for favorites activity, when a search is performed the
result will clear the fill map only if it is the first page index,
otherwise it will append onto the existing fill map. This allows for
paging functionality.
