Added ability to adaptively change display units to a more appropriate range on numerical property editors. This behaviour can be disabled with a AllowUnitRangeAdaption=False meta tag.
Spin boxes now accept a numeric type interface which allows customization of numeric handling.

#change Replaced CLASS_Temporary (UHT-only flag) with CLASS_Constructed to check if a class needs to be constructed or not in generated code
#change Modified code generator to make sure UClasses don't get reconstructed if not required

In order to use new feature user have to change GENERATED_UCLASS_BODY() macro to the new GENERATED_BODY(). Then no constructor is implicitly declared. If there is no constructor declared in UCLASS then PCIP one is declared and defined that passes PCIP down to super-class. On the other hand if there is a constructor declared then UObject system expects to have one of the default or PCIP constructor to initialize a class during loading from disk, default object creation, etc. and it expects that user will declare and define one.
There is a possibility now to create UCLASS with the default constructor (i.e. no PCIP).
New macro is encouraged by standard classes and in-editor wizards templates.
