Why does Sporran ask for clipboard read and write permissions?

Sporran has a "read clipboard" permission that enables it to read the recipient address from your clipboard and to paste it into the "recipient address" field, making the process easier for the user.

Sporran also has a "write clipboard" permission that, similarly, makes the process simpler by enabling it to write your KILT address into your clipboard when you are receiving KILT Coins.
