Add gitignore template for Automation Studio 4 Projects

[shanereetz]

Reasons for making this change:
B&R Automation Studio is an IDE for developing industrial software for Programmable Logic Controllers (PLCs). B&R is part of the ABB group and is one of the major names in industrial automation software. I work for a company, Loupe, that develops open-source libraries and custom software for this platform, and other automation platforms like Beckhoff TwinCAT that support modern software development practices.
