This patch fixes a problem with OptRegexp. The OptRegexp class is
always forcing the value to be converted to a string first, which
causes the EXCLUDE option in browser_autopwn to kick in and match
every found autopwn module, so it ignores all of them and you load
nothing (#4616).
It is important to understand that nil actually represents an option
not being set, which is a completely different behavior than having
an empty value (technically "" is still a value, and if there's a
value, it means the option is set). We need to watcher for these
scenarios.
I am restoring the #default method to avoid forcing a to_s, which should
fix the browser autopwn loading problem. And then I changed scraper.rb's
default value for datastore option PATTERN to a string, because still
fixes#3798. The way I see it, #3798 is actually a module-specific issue.
