Ajax request error handler added to plugin

statusEvent parameter added to request method. It define what's happen
when a non expected response occured from ajax request. Each API methods
can define it's own statusEvent but by default if no statusEvent is
provided then statusDefault is called. statusDefault can be overwritted
in the user interface application.
