Malformed URL when retrieving files

[JonZeolla]

There appears to be an issue handling the oinkcode where it doesn't add a / appropriately between it and the domain.

Use of uninitialized value $Snort_path in -B at ./pulledpork.pl line 1773.

In my conf I have

rule_url=http://rules.emergingthreats.net|emerging.rules.tar.gz|open

If I change that to

rule_url=http://rules.emergingthreats.net|emerging.rules.tar.gz|/open

It appears to work properly.

This also works when you use:

rule_url=http://rules.emergingthreats.net/|emerging.rules.tar.gz|open

I don't believe that / used to be required, but now it is. Perhaps it's worth detecting if the domain ends in /, and if not, add it.
