Process all tools before erroring

[ghostnaps]

My team relies on several tools that are located in private repositories (Rotriever is one example), and because my team intends to make our projects source-available, this leads to regular users being unable to install public tools like Rojo, Selene, and StyLua due to an authentication error.

Foreman should process every tool and only error at the end if there were any tools it could not install. This will ensure all public tools will be installed.
