Final tweaks to download items on OS X.

Final tweaks to download item look on OS X. It now looks pretty much like on windows and linux, but is drawn nearly completely with vectors.

Also fix the SkColor->NSColor conversion in the mac theme provider.

Also let status bubble text color be influenced by current theme.


BUG=18902, 18438
TEST=Download items now look like on windows. Color of the main download item text should change with the theme. Also, the status bubble text now adapts to the theme, and themes that specify text colors can now successfully change the color of e.g. the text in tabs. Also check that the status text ("104.0/110 MB, 1 h 45 secs left") is elided at the right when it's too long.

Avi, since this is theme-related, I'm sending this to you.

I've put screenshots of the windows and mac download shelfs on top of each other
and made sure everything lines up. Ben asked me to make the mac items a
pixel-identical copy of the windows items (modulo color, fonts), which is now
the case.

In my eyes, the popup arrow is now two pixels to high ;-)

Yes, I am appropriately embarrassed. :)
