Unable to switch between icon and image display

[alberthier]

See this jsbin: http://jsbin.com/boruva/edit?html,output

I would like to switch between the polymer logo and the 'check' icon using a single <iron-icon>
The 'Toggle' button sets/unsets the icon and src properties

As long as you use the same image type you can change the image as much as you want. But switching from icon to src doesn't work

PR #48 fixes this issue

/cc @azakus (maintainer) @kevinpschaaf (TL) @tjsavage (PM)

this would be nice for Chrome's UI as well, and PR #48 seems legit.

i was about to file an issue with a similar repro (http://jsfiddle.net/t8na1wop/).

Fixed with #48
