GitIgnore + AutoBuild + Cleanup + Fix version

[Julienraptor01]

This PR adds :

• GitIgnore to prevent uploading unnecessary files (cause i'm using VS2022 and removing stuff like builds and vs specific files is annoying)
• Build action based on the one from Ultimate Crosspathing (thanks @doombubbles)
• Removal of the warnings by cleaning up the usings (i just used the clean in VS2022)
• Fix the version not being 4.1.0
