better module error handling

Browse source 
* now module errors clearly state msg=MODULE FAILURE
* module's stdout and stderr go into module_stdout and module_stderr keys
which only appear during parsing failure
* invocation module_args are deleted from results provided by action
plugin as errors can keep us from overwriting and then disclosing info that
was meant to be kept hidden due to no_log
* fixed invocation module_args set by basic.py as it was creating different
keys as the invocation in action plugin base.
* results now merge
