Resize and overflow for browser actions (part 1).

This changelist implements the following:

- A resize gripper and chevron in the browser action container
- Overflow when icons don't fit
- Snap to multiple of icon size (no excess pixels)
- Animation when resizing container / adding&removing icons (disable, enable).
- Persists the last width of the browser action container.

Known issues:
- No menu (yes, the chevron button doesn't do anything yet).

BUG=32101
TEST=Install and uninstall browser actions & make sure install bubble appears in
the right location. Make sure browser action container does not expand if
chevron is showing when you add browser action. Make sure container loses
chevron when no overflow occurs. Make sure browser action icons never disappear
due to shrinking when you release the mouse (when resizing). Make sure snapping
works.
