Annoying things

[EugeneN]

• backend loses connection (infinite http request, with data frames separated by \r\n) with twitter api server, but can't detect it. There is some algorithm implemented to check for stalls, but it works inefficiently (fixed in 5ae38d3).
• virtual-dom fails to patch event listeners properly. This results in new nodes firing event handlers with data from previous generation (possible fix: don't patch, replace everything every time) (fixed in EugeneN/haskell-virtualdom@d659f72)
• html entities encoding ("&")
• unicode emoji (mis)encoding
• truncated tweet body
• not all embeds are shown
