minor improvements, corrections (#180)

- comma must follow "additionally" and "however" as they are introductory words or phrases
- same for "last but not least", comma missing
- "nothing else than", not perfect English; better "nothing but" 
- "get most use", not perfect English; better "get more benefits"

+Additionally, these contracts have the option to connect channels in a way that one can forward payments from one channel to another.
 For example, Alice can send money to Bob if Alice had a channel with Mallory and Mallory had a channel with Bob.
 By the design of the Lightning Network, it is possible to extend the smart contracts which operate the channel so that Mallory has no way of stealing the funds that are being routed through her.
 Not only does the construction of the payment channel work for the partners without the necessity to trust each other but the entire network works without the necessity to trust any other participant.
 Since the channels are funds on multisignature addresses and as the contracts are unpublished but presigned Bitcoin transactions, all the trust that is needed to operate the Lightning Network comes from the trust in the decentralized Bitcoin network!
 
 The aforementioned innovations are certainly the major breakthrough that allow the creation of the Lightning Network.

+However, the Lightning Network is so much more than the cryptographic protocols on top of the Bitcoin scripting language.
 It is a full communication protocol that allows peers to communicate with each other via Lightning messages to achieve the transfer of bitcoin.
 The communication protocol also defines how Lightning messages are being encrypted and exchanged.
 A gossip protocol is part of the specification that is used to share public information about the topology of the network with the other participants.
-This information is needed for Alice to be aware of the fact that Mallory has a channel with Bob so that she can decide to send a payment via Mallory to Bob.
