* fixed bug along error path in quantum_network module
* user password update mode is controllable in user module now (creation vs every time)
* added check mode support to the OpenBSD package module
* internal system by which a module can process multiple with_items entries is now streamlined (see yum, apt, etc) so any module can request this behavior. If used, parameter given to {{ item }} will be joined by commas and passed once, rather than invoking the module N times. Previously this was available to a select few packaging modules only. Now any module can specify WITH_ITEMS_USES_LIST in the source and get this behavior.
