Organize project structure into 📁 sub-folders dividing GUI components from core API.

Divide API into 📄 simple components following some good practices.

Rename variables and members into clear , consistent, and homogeneous names (no more 🇫🇷➕🇬🇧 french-english mixing, 🔤 unclear abbreviations, and 🎲 random letter casing) following some good consistent 📕 naming conventions.

Remove useless 🗨️ comments (Code must comment itself or use reasonable comment that tells something unclear from the code itself).

Replace many created 🔧 utility functions with better .NET available alternatives.

Upgrade .NET Framework from v2.0 to v4.0 allowing the use of 🔩 extension methods for better 🔧 utility functions use.

Turn program native language (Text in GUI, Code, and Database) fully to 🇬🇧 english instead of 🇫🇷 french (It should be 🇬🇧 english by default if there's no language resource set).

Update the GUI following some good 📕 Windows GUI standards (No more weird inconsistent incoherent colors and fonts on the controls. Either follow the native Windows look or use custom controls library).

Update 📖 README.md file with some infos and fancy screenshots 😆.
