ActivityType API should return activity_type_id with get

The get action of the ActivityType entity only returns the names of the ActivityTypes
however in Activity types are referred to by activity_type_id, these are not returned by get
so its results are of limited use.

It should return the name and corresponding activity_type_id

In my code I want to see if an ActivityType already exists and if it does use its activity_type_id in creating an activity. The first is possible the second is not.

civicrm/api/v3/ActivityType.php uses the CRM_Core_OptionGroup::values function.

function civicrm_api3_activity_type_get($params) {

$activityTypes = CRM_Core_OptionGroup::values('activity_type');

This is problematic as the function itself notes:

• This function retrieves all the values for the specific option group by name
• this is primarily used to create various html based form elements

this doesn't seem a likely use case for the API, certainly not the REST API.
