The image icon was not clear enough. The editor bar appears in the
website builder, the mail composer, the forum composer, ... In each
of them, we can both link a picture or a file but a picture makes
more sense in some context and in some other ones not.
This commit solves the problem by changing the icon to fa-file-image-o
which is a mixed of file and image. This also solves the problem of
having two buttons with the image icon in the website builder (indeed
an image icon is also used for the image look button).
