workflow_ng 5.x-1.1

This is an bug-fix release :)

changes since 1.0:
#183699: improved the content publish / promote actions to only cause content saving when they are actually changing something
#183699: removed the last fix for automatical saved arguments and implemented a better one.
#183699: fixed problems with automatical saved arguments, which occured with php4 or non objects. now arguments may be also passed through an associative array, which one can use for passing references
#176629: fixed problems with php4 & array_intersect_key
#178759: fixed problems sorting of actions by weight, if weight is 0. also fixed saving the argument map for newly added actions and conditions
added missing properties to the provided example default configuration, so that detecting configurations changes for the reset mechanism works more reliable
