Add a set of default patterns to ignore.
Add a set of default patterns to ignore.

* adm_crawler.c (add_default_ignores): New function.
(report_revisions): Initialize the "patterns" hash here, and hence
don't worry about it being NULL.  (load_ignore_file): Adjusted to take
a real hash rather than pass one back.
