Appears to have stopped working on SF sandbox due to URL change

[seanpd]

Sometime in the past week it no longer accesses the SF sandbox.
I think SF changed the URL so the #parse_instance regex no longer recognizes it.

This monkeypatch makes it work again:

module SalesforceBulk
 class Connection
   def parse_instance()
     m = /https:\/\/([a-z]{2,2}[0-9]{1,2})(-api|\.)/.match(@server_url)
     return '' unless m
     @instance = m[1]
   end
 end
end

The @server_url used to look something like https://cs14-api.salesforce.com/services/Soap/u/24.0/x
but now it looks like https://cs14.salesforce.com/services/Soap/u/24.0/x
The orig code wants the '-api' there.
