Let copy a property during creation of document types

[manninofrancescoyourbiz]

Hi, during my use of Umbraco, I noticed that it would be very comfortable if I could copy a property.
This idea is already implemented for document types (now you can copy a document types).

Why

I think it could be useful when properties are similar in terms of data type and flags like allow varying by culture.

Another good point could be that in this way you could simply reuse data types in various properties (avoiding to create thousands of similiar data types).

Example

If I need to create a Title property and a Description property and I need an RTE with the same configuration for both, I shoud be able to:

1. Create the Title property
2. Copy it and the system should create a "title1" property (like Umbraco does with doc types)
3. Rename the "title1" property in "description" property

In this way I'm sure that all configuration of title property (allow varying by culture, data type, mandatory flag ecc.) will be copied in the description property.
