BIP-0039: just adapt number of rounds and test vectors
Correct maven instruction in the README file and make ForwardingService work on mainnet again by fixing command line arg parsing.

Resolves issue 523.
Remove incorrect execution of OP_0. That code was never reached, because OP_0 is not an opcode in terms of chunk.isOpCode()). However, it lead to believe that OP_0 pushes the vector [0], rather than correctly the empty vector to the stack.

Because the code was never executed, this bug could never trigger a test. Afaict, script.cpp does not have the corresponding case in its switch block.
This changes the ignored stack element CHECKMULTISIG bug workaround from the [0] vector to just the empty vector, by using the opcode OP_0 rather than 0x4c 0x00.

Afaict, this is also the workaround behaviour of script.cpp, which uses OP_0, pushing an empty vector. This saves one byte in multisig input scripts.
Remove OP_0 from Script.encodeToOpN() and .decodeFromOpN(). It was incorrectly assumed that OP_0 pushes a [0] vector to the stack. In fact, it pushes the empty vector.
