Rules E-notice - need to standardise function names & object names

I am hitting E-Notices in the Rules module & it seems to me to about a standard that we should get in place now. It's definitely one of those things that will be trickier the longer it is left.

The E-Notice I see is
Notice: Undefined index: type in rules_core_action_transform_info() (line 329 of C:\webroot\egw\sites\all\modules\rules\rules\modules\rules.rules.inc).

I'm not seeing it happening for the actions I have been creating (on my local machine) and the difference appears to be whether the action name correlates to the data type name

e.g
rules_action_civicrm_add_to_group
will give a notice but
rules_action_contact_add_to_group
is OK ('contact' is the name of the datatype)

A related issue is that in some cases the civicrm entity is prefaced by 'civicrm_' & in others it isn't.
So the data type is : 'mailing'
but there are functions such as 'rules_action_civicrm_mailing_send_email'

I think we DO need to preface our entities as entities like 'event', 'group' and 'phone' will otherwise conflict with other Drupal modules & this was the primary reason I set up the functions I added in a separate file - because I didn't know how to deal with what was there already.

Ideally we would rename them all to one convention but this will break existing implementations so I think we need to
1) agree the standard (my vote is 'civicrm_contact', civicrm_mailing', 'civicrm_participant')
2) change functions like
function rules_action_civicrm_add_to_group_form(){
blah
}
to be

function rules_action_civicrm_add_to_group()

{ //I'm now a wrapper function rules_action_civicrm_contact_add_to_group(); } }
