Subclass of ResourceBundle with special
functionality for time zone names. The additional functionality:

Preserves the order of entries in the getContents
    array for the enumeration returned by getKeys.
Inserts the time zone ID (the key of the bundle entries) into
    the string arrays returned by handleGetObject.

All TimeZoneNames resource bundles must extend this
class and implement the getContents method.

Maps time zone IDs to locale-specific names.
The value returned is an array of five strings:

The time zone ID (same as the key, not localized).
The long name of the time zone in standard time (localized).
The short name of the time zone in standard time (localized).
The long name of the time zone in daylight savings time (localized).
The short name of the time zone in daylight savings time (localized).

The localized names come from the subclasses's
getContents implementations, while the time zone
ID is inserted into the returned array by this method.
