Make RBClient cookie_file optional

If a cookie_file is not provided it will now default to
'~/.rbtools-cookies'. Also, if we default to '~/.rbtools-cookies' and
it does not exist, we will attempt to copy the old
'~/.post-review-cookies.txt' file over.
Accessed the API using default and provided cookie files, observed proper behaviour.
