Track user generosity
add detail to readme on new commands
refactor: create sendTo command, accept array of responses

The sendTo(destination, message) command can now be used to send a
message to either a channel or a user. The main computeResponse loop
has also been modified to return an array of reponses to allow bamboo to
respond with more than one line.
Generosity now in correct order
