The first time "make release" is run, it errors out with "rm: cannot remove './frontend/cfviz-frontend': No such file or directory"

Since ./frontend/cfviz-frontend does not exist yet.

The solution is to use rm -f.

Do not complain if frontend/cfviz-frontend does not exist (fixes #20)

This happens the first time the project is built after being checked out.
