reverse mode: support wildcard exclude (--exclude-wildcard)
This adds support for gitignore-like wildcards and exclude patters in reverse mode. It (somewhat) fixes #273: no regexp support, but the syntax should be powerful enough to satisfy most needs. Also, since adding a lot of --exclude options can be tedious, it adds the --exclude-from option to read patterns from a file (or files).
