Change socket color for realistic bulb

[samreid]

Related to #10. At today's design meeting, we agreed the realistic bulb should look different than the ideal light bulb, and this may be done by drawing the socket differently. High priority since we would like to publish this soon.

Here are the bulbs currently in CCK:

In design meeting we discussed making the socket a metallic-looking red. Here's a mockup with the coiled filament (see #614). @samreid if this color looks reasonable to you, I'll send you the asset.

That seems good to me. Do you want a 2nd opinion from @ariel-phet before we proceed?

[ariel-phet]

I like that red color, definitely makes it stand out.

[arouinfar]

Great, thanks! The final assets will be delivered once we're done iterating on #614.

[arouinfar]

@samreid the updated assets are linked at the bottom of #614 (comment).

I added the images in the commit. To see them in the toolbar, you might need to remove the pencil (until another issue is fixed). Other than that, can you please review?

UPDATE: On second thought, there is a problem with the socket in the toolbox. Self-reassigning.

[samreid]

OK I think that commit will help. Ready for review.

Looks great in master, thanks @samreid!
