transaction: remove all refs to segwit and bech32

dogecoin does not currently implement segregated witness otherwise known as segwit, therefore i've removed all references to segwit and bech32 address encoding.

-transactions revolve around a structure defined as a `working_transaction` which is comprised of an index as an integer meant for retrieval, a dogecoin_tx 'transaction' structure as seen above, and finally a UT_hash_handle which stores our working_transaction struct in a hash table (using Troy D. Hanson's uthash library: see ./contrib/uthash/uthash.h and visit https://troydhanson.github.io/uthash/ for more information) to allow us to generate multiple transactions per "session".
