WPSClient - only show abstract if it is set (i.e. do not display a nasty "null" text to user otherwise)
WPS - store Process Status within Process after execute() call
WPS - store status abstract (i.e. description within <wps:Status> element)
WPS - corrected issue : status and statusAbstract where not stored
mapshup - add a missing semicolon
WPSClient - correct issue #3 : add support for asynchronous processes
