BitBucket doesn't implement support for PR comments or issues comments.
The current implementation of "pullService" in BitBucket defers to the implementation of "issueService", which itself returns a "not implemented" error for all comment-related calls.
PR comments and issue comments are separate in BitBucket so this commit adds explicit implementations of the comment functions to the "pullService". Most remain "not implemented" with the exception of comment creation which is now supported.
