Only finalize the TPythonEngine after remove all clients

What steps will reproduce the problem?
1. Programmatically setup a TPythonEngine instance.
2. Programmatically create modules (clients).
3. Each module creation/destruction generates a new TPythonEngine instance.

What is the expected output? What do you see instead?
The issue consists that for each module creation/destruction a new 
TPythonEngine is created, taking time on loading the python dll.
I want share the same TPythonEngine across multiple modules 
creation/destruction. 

What version of the product are you using? On what operating system?
Trunk clone.

Please provide any additional information below.
I'm using P4D to access a template engine (Jinja2) from Delphi, to render out 
our reports.

I'm sharing the source code that fix this issue.

Tks in advance.
