Remove Tx model

Browse Source 
There was a split between a transaction request and an actual
transaction. This was kind of annoying because transactions were one-way
only, while transaction requests were two-way - which is what I believe
most transactions will be using. Tx model has been removed and the
responsibilities of it are covered by TxRequest. It simplifies
everything surrounding transactions, since we have only one model to
deal with instead of two.
