SMW 1.9 compatibility

#set_internal_recurring_event and #set_recurring_event are now
interchangeable

Difference between #set_internal and #subobject are
* #list vs +sep=
* auto in-page reference (which would be rather easy to implement because
'SMW\RecurringEventsParserFunction' already does it )

SIO has no unit tests, so I used the following for verfication:

{{#set_internal:Some hunger
|property1=value1
|property2=value2
}}

{{#set_internal:Part of recipe
|Has quantity=1
|Has unit=cup
|Has ingredient=flour
}}

{{#set_internal:Is president of
|Has name=Ulysses S. Grant
|Has vice president#list=Schuyler Colfax, Henry Wilson
}}

{{#ask:[[Part of recipe::+]][[Has ingredient::flour]][[Has unit::cup]][[Has quantity::>.5]]
|mainlabel=-
|? Part of recipe
|? Has quantity
}}

{{#set_internal_recurring_event:Is instance of
|property=Has sio date
|start=January 4, 2010
|end=June 8, 2011
|unit=week
|period=1
}}

{{#ask:[[Has sio date::>February 1, 2010]][[Has sio date::<February 7, 2010]]
|mainlabel=-
|?Is instance of
|?Has sio date
}}
