GTK: Initial implementation of using GTK themes, partially based on evan's CL 118358.

A lot of stuff works:
- Colors are picked out of the GTK theme.
- Buttons use the current GTK button theme.
- We use the user's icon theme.

A lot of stuff doesn't:
- We could do a better job of picking colors for the skylines.
- The omnibox hasn't been touched.
- UI that's not part of the toolbar hasn't been touched.
- We currently fail on themes like HighContrastInverse.

TEST=Under Options>Personal Stuff, click GTK Theme. Colors and widgets should be rendered with the current GTK theme stuff.
TEST=With chrome open and in GTK Theme mode, change your GTK theme or icon theme. chrome should pick up on the change immediately and reimport the colors and images.
