Add support for image

[Bluebugs]

Both iterm2 and terminology offer the ability to include an image in the stream of the terminal. This is very practical and useful feature as you can "cat" quickly file like fyne test data and see if things like OK. It would be great to eventually bring this feature in.

Oh yeah this would be cool.
Is there any sort of standard for inlining images (escape codes perhaps?)
I seem to remember that Terminology had some custom code and a command that went alongside (tycat?).

Both in the case of iterm and terminology, they have a custom combination of time that means here is a path to an image, please put it in the stream. I will have to look at the documentation/ code to find it. Will do later when I am in front of a computer.
