Add hook for non-breaking space in 0 A.D.

This replaces the existing arclint linter to ensure the project name
does only include a non-breaking space with a pre-commit hook. The regex
to check is slightly different to account for escaped non-breaking
spaces in JavaScript files and to avoid some false-positives.
