Fix comment replies

Comment reply protobuf now requires the channel id of the uploader
of the video. Otherwise the endpoint returns 500.

Instead of making the protobuf ourselves and passing this data
around through query parameters, just use the ctoken provided to us
but modify the max_replies field from 10 to 250.

Fixes #53
