Images from Telegram are not translated to XMPP

[ForNeVeR]

Try to post image to Telegram. It won't cause any measure effect on XMPP room. That's inappropriate.

At least show something like [Image posted], but better repost the image to some server (probably keep it on your own Heroku instance) and post the link to XMPP.

Hey, there's XEP-0363: HTTP File Upload, and this feature is enabled on jabber.ru. Bot should use this feature to upload images if available.
