Suggestion: allow base64 encoded images

[rgerard]

For the image object, it would be nice to allow small images to just send back their base64 encoding, as opposed to the URL. Something like this:

"16s": {
"height": 16,
"width": 16,
"base64": "iVBORw0KGgoAAAANSUhEUgAAABAAAAAQCAIAAACQkWg2AAAABmJLR0QA/wD/AP+gvaeTAAAACXBIWXMAAAsTAAALEwEAmpwYAAAAB3RJTUUH1woICQIzztyOYgAAAHVJREFUeNpj/P//f3t7OwNuICwsnJaWBueyQKjExABcGjZtOhwWFrZq1SoUDRISmrjtOLxq1Sq4HiYGIkBYWBicZCGoOi0tzcjIiIGBoauriygNDAwMJiYmcDZRTkIGoxpoogEacWfPniVBw/nz58+fP0+kBgCxLR/Dk4eUOQAAAABJRU5ErkJggg=="
},

In a project I worked on a while back, we had to fetch tons of small images from urls. We instead started sending down the base64 encoding instead of the url, which saved us a round-trip in fetching the image. For a small image like this (16 x 16), the extra bandwidth to send the encoded text is negligible compared to the cost of opening another http request and pulling down the image.

No, I didn't. I used the number 3 in a comment and it put in this reference.
