Separate options for pride do to ignore errors and to fail late

[lptr]

Right now there is a pride do --ignore-errors option that does just that: if there's an error, we continue working on the next module, and we don't show anything in the process's exit value.

We'd need a --fail-late option as well, i.e. when there's an error, we should continue with the next module, but in the end provide a list of modules with errors, and also change the exit value.
