Popover requires gtk+ >= 3.18
Created by: hannenz
I compiled gradio successfully on elementary freya (which is ubuntu 14.04 basically; shipping gtk+ 3.14) but when running the popovers are empty and gtk issues
Error building template class 'GradioActionPopover' for an instance of type 'GradioActionPopover': <input>: required gtk+ version 3.18, current version is 3.14
in the terminal.
So, please update the requirements section to reflect this. Will check again when elementary loki is out, which should ship with gtk+ 3.18
