Bots login via token#
Added support for bots login; pass your bot token when creating a Client to login as a Bot instead of a User.
Added support for sending messages to private supergroups or channels using valid
t.me/joinchat/links, e.g.: https://t.me/joinchat/AWDQ8lK2HgBN7ka4OyWVTw.
Added support for downloading media in custom locations using custom file names as well. Thanks @EriHoss.
Schema updated to Layer 76.
Set Python minimum version to 3.4. Goodbye 3.3 (EOL).
Lots of minor fixes and improvements.
