Localizing manifest for installed or unpacked extensions.

1. Use _MSG_ format for manifest fields instead of hard-coded names.
2. Localize manifest during installation procedure -> save localized version to prefs.
3. Add current_locale field to manifest so we can detect when chrome locale changes and re-localize manifest.
4. Adds prefs method to MigratePrefs&Write to disk.
5. General refactor of extension_file_util wrt l10n code.
6. Don't localize themes (we can revert this by adding default_locale and current_locale keys to allowed keys for theme section).
