WebUI TaskManager: Supports background-page mode.

WebUI TaskManager: Supports background page mode.

A background-page-moded Task Manager can be lunched by selecting "View Background Pages (xx)" on the menu, which is shown only when any background page is present.

When background-page mode is enabled, the row of background tasks are hi-lighted.

Could we pass backgroundMode from outside instead of referencing location.hash
in here?

Should we use table instread of this.table_?
