Telegram released bot API v3.6

Adjustments needed to the library:

• Supported text formatting in media captions. (should work out of the box)
• In supergroups, if the bot receives a message that is a reply, it will also receive the message to which that message is replying – even if the original message is inaccessible due to the bot's privacy settings. (should work out of the box)
• Added the new field connected_website to Message. (bool)
• Added the new parameter supports_streaming to the sendVideo method
• Added a field supports_streaming to the inputMediaVideo object.
• Change https://travis-ci.org/python-telegram-bot/python-telegram-bot/jobs/341799350#L1860 to expecting a BadRequest: Media_caption_too_long instead of just cutting
