Schedule a reconcile if the chrome accounts change.

The chrome accounts may change while a reconcile operation is in progress.
The account reconcilor currently ignores refresh token events when a reconcile
operation is in progress.
This CL checks if the accounts change while a reconcile operation is in 
progress and starts a reconcile operation if needed.

Fix Views find-bar textfield border and background drawing.

The IDR_FIND_BOX_BACKGROUND[_LEFT] assets have white fill.
These yield white textfield outlines with custom OS themes.

Paint the text background and border similar to the Omnibox.
Limit the old assets to their only remaining build (GTK).
See before/after pics at http://crbug.com/319103

TODO(followup): Nix IDR_FIND_BOX_BACKGROUND[_LEFT] post-GTK.
TODO(followup): Rename IDR_OMNIBOX_BORDER_AND_SHADOW_* to IDR_TEXTFIELD_*.

TEST=The find bar looks good on Win, CrOS, and Linux Aura when high-contrast-black/inverse OS color themes are used. No other find bar changes.
