[IMPROVE] Modularize project into packages. (v1.15)

[alfredo-f]

WHAT

Improve project structure by modularizing different components.

WHY

1. Improve the process of adding new features
2. Improve maintainability
3. I am Italian, but still I can't develop with this kind of spaghetti :)

HOW

1. Create a separate package python_easy_chess_gui
2. Move all constant global variables to config
3. Move classes to 3 main sub-packages

• engine_package
• play_package
• ui_package

4. Parametrize with global variables the folder paths

• Book
• Engines
• Icon
• Images

@alfredo-f have you tried converting this to windows exe using pyinstaller? All my attempts so far in creating an exe were unsuccessful.

Never mind, I got it now.

New issue, I can build an exe, but I cannot save the new installed engine in json. After restart, the new installed engine is not there. And I cannot find the engine json file. Perhaps the json files should be saved outside of the python_easy_chess_gui folder.

I can fix this now. This is due to ROOT_PATH definition. It has to be defined also with executable.

@alfredo-f

These are the issues that I found, the windows executable that I built complains about these issues.

1. Define the string properly example.

engine_config_file = ROOT_PATH / 'pecg_engines.json'

With f string it should be:

engine_config_file = f'{ROOT_PATH}/pecg_engines.json'

A lot of these are in config.py.

And here.

2. In the init, detect if the app is an exe.

Awesome! Can you push the changes?

I have an error when trying to push some changes.
