Moved Bunch of functions from net_crypto to crypto_core. decrypt_data_fast and decrypt_data_symmetric were the same thing therefore, removed decrypt_data_fast. Replaced all the crypto_secretbox_* defines with the equivalent crypto_box_* one. New define: crypto_box_KEYBYTES that is equal to crypto_box_BEFORENMBYTES.
