Address ticket #1145: Qty in search result zero, but OH correct elsewhere.
   The Qty column isn't the On hand column, but can be easily mistaken.
   Putting On hand in the search result by default instead.
Initialize logging system before using it.
Correct Apache2 URI -> script mapping for the rest script.
Comply with 'use strict' coding restrictions.
Multiple fixes:
 - $cgi->self_url() points to the script; which our URLs don't include
 - initialize logger framework to prevent errors from modules trying to use it
 - the URL should be .../rest/... (instead of .../rest-handler.pl/...)
     since we use the former in our template httpd config
Include reference to hard-coded path in configuration file.
Rename rest handler class to get all-lower-case URLs.

--HG--
rename : LedgerSMB/REST_Class/Contact.pm => LedgerSMB/REST_Class/contact.pm
Class rename required due to file rename.
