new_chat_participant in Message was renamed to new_chat_member in 2016

[khng300]

Although most of the time people shall use new_chat_members for the current API standard, new_chat_member was still available for backward compatibility. Maybe we should consider the change also to be more aligned to the spec?

Miscellaneous

Added new objects MessageEntity and Venue, new methods sendVenue and sendContact. Renamed the fields new_chat_participant and left_chat_participant of the Message object to new_chat_member and left_chat_member.
