Updated conCfg and VendorCon and removed stdCon

Updated these functions where you can use either the conn.cfg.php file
or pass in the appname and apikey. Also changed the version number to
represent the App version when the sdk was updated. This makes it easier
to debug for future use.
Fixed $debug= "off". Missed making that backwards compatabile
Cleaned up code con cfgcon and VendorCon
added Affiliates to OrderService.placeOrder
Fixed connection issue.
Fixed connection issue with variable name
fixed cfgCon when 'kill' is passed in
cfgCon not behaving as it should fix
Remove CamelCase

Mismatched variables ($appName, $appname) was causing the
"connectionName" parameter from conn.cfg.php to be used in $appname
instead of the "applicationName" parameter.
