[Geary] new ideas for the spam/junk icon in Geary

[Federico Bruni <fede inventati org>]

Hi folks

I've added a comment in this bug:
https://bugzilla.gnome.org/show_bug.cgi?id=737862

but I'd like to ask for feedback here about the current spam icon.
Do you like it? Do you think that it communicates well its meaning?

Personally, I don't like it (I guess that I have some "political view" 
about it.. I'm veg).
But, most importantly, I think that it's not easy to catch its meaning. 
Of course there's the text besides it which explains it clearly. But 
still the icon seems awkward.

I would suggest to use a simple hexagon with a centered exclamation 
mark (similarly to the spam button in Gmail).

What do you think?

Cheers
Federico
