Add runtime option to always use the constructor from sun reflection factory

[GoogleCodeExporter]

-Dprotostuff.runtime.always_use_sun_reflection_factory=true

If true, the constructor will always be obtained from 
ReflectionFactory.newConstructorFromSerialization.

Disabled by default, which means that if the pojo has a no-args constructor, 
that will be used instead.

Enable this if you intend to avoid deserializing objects whose no-args 
constructor 
initializes (unwanted) internal state.  This applies to complex/framework 
objects.

If you intend to fill default field values using your default constructor, 
leave this disabled. This normally applies to java beans/data objects.
