[Bf-python] Adding objects and scenes refactor

[Campbell Barton]

Making Object_New create its own data would be bad if you had a script 
that made linked duplicates-
Before the array modifier I had an array script and made many objects - 
up to 1000s,
if every Object_New created obdata it could make a huge ammount of empty 
obdatas,

My fav solution is to make Object_New accept obdata.

ob= Object.New(mymesh)

Maybe the old way could make data instantly and the new way- above would 
allow you to add an object with existing obdata.
