goodbye LogWriterI18n

[Bruce Schuchardt]

I've just checked in a fairly large set of changes to remove all uses of 
LogWriterI18n and to remove the LocalizedStrings.java class altogether.  
The other I18n classes are still in place because they are in a public 
package or are needed to make that stuff compile, but you should no 
longer use them.

From now on please use the new log4j-based log service.  If you must 
use a LogWriter do not use the LogWriterI18n variant because you no 
longer have a good framework for creating StringIDs to feed to its 
methods.  Just use regular Strings.
