[mythtv] Service API RecordSchedule shortcoming

[Peter Bennett]

When creating or updating a recording schedule with the service API, you 
can specify a Recording Group (recgroup). However if you provide a new 
recording group, the service API disregards it and sets the Recording 
Group to "Default".

There is no service API method to create a new recording group.

In MythFrontend, recording groups are created just by entering a new one 
when setting up a recording rule.

Note there is no way to delete a recording group, either with the 
frontend or the API.

I propose to change the Service API so that it will create a new 
recording group if one is supplied that does not already exist. This is 
in line with how the frontend works, and will solve my problem.

Anybody have any comments or objections?
