Refactor build script

Summary

Make the build script more easy to read, and using high level functions instead of low level ones. I added cqtdeployer check on Linux that disable deploy if it wasn't found and I also added some python to .gitignore (because when you run python script it may create a __pycache__ folder). And last change, you now need to execute it in ScreenPlay root directory (beacuse the old script suppose you execute it in the Tools folder, and it'll still cd to parent directory)

Note that I haven't tried this build script on Windows/macOS yet but I think it'll still work, so if someone can test it for me I'd be very appreciated
