Subject: [PATCH] Browser: Add a special context menu for images

Now, right-clicking on an image allows you to open that image in this
tab or a new tab. You can also copy the image URL, and even copy the
image itself to the clipboard! :^)

Copying to the clipboard will not work in a multi-process context yet,
since we need to send the image bitmap across the IPC boundary and this
patch does not do that.
