Add remaining items to Chrome App menus. (Mac)

These are disabled as they are not yet implemented. They are being added
now primarily for aesthetic reasons, on advice from UX.

Menu items added:
<app> -> About <app>
File -> New
File -> Open File

Menu items removed:
Edit -> Find

This also adds a new resource string for "New", and NSTags to various
NSMenuItems in MainMenu.xib.
