v1.21.0

Add support for enforcing regex rules on PR Title (#256)

Adds functionality for disapproving pull requests which do not comply by defined title formatting requirements as mentioned in #244.

• A new predicate title is added for defining allowed (not_match) and disallowed (match) regex patterns on a pull request title.
• The disapproval policy is extended to allow predicates just as individual approval_rules do. However, whereas an approval rule may only allow approvals subject to passing predicates, the disapproval policy will only allow disapprovals subject to its own predicates all failing. Passing predicates on the disapproval policy will trigger a default disapproval, just as failing predicates on an approval rule will implicitly approve (pass).

Add support for handling review comments (#257)

Adds support for handling review comments like regular comments, thus allowing users to approve or disapprove without switching back to the "Conversation" tab of the pull request whilst reviewing the changes. Fixes #51.
