Make ReceiveTransactionFragment extend from ConnectedFragment to reduce boilerplate and repeated code. Change the method used to obtain the Assets list from the db in ReceiveTransactionFragment, it now retrieved only those Assets for which the user has a Balance > 0. Improve ReceiveTransactionFragment's function that obtains the suggestions for the AutoCompleteTextView when the user wants to receive a different Asset, to avoid crashes if the information received does not have the expected format.
