bpo-38293: Allow shallow and deep copying of property objects (GH-16438)
 

Copying property objects results in a TypeError. Steps to reproduce:

```
>>> import copy
>>> obj = property()
>>> copy.copy(obj)
````

This affects both shallow and deep copying.
My idea for a fix is to add property objects to the list of "atomic" objects in the copy module.
These already include types like functions and type objects.

I also added property objects to the unit tests test_copy_atomic and test_deepcopy_atomic. This is my first PR, and it's highly likely I've made some mistake, so please be kind :)

# Fixes encoding of the project files to add UTF-8 BOM.
#
# Visual Studio insists on having the BOM in project files, and will
# restore it on first edit. This script will go through the relevant
# files and ensure the BOM is included, which should prevent too many
# irrelevant changesets.
