* update some exceptions that were not returning proper codes:

2008-10-10 (Fri, 10 Oct 2008)
* MailChimp API v.1.1.1 release 
* no existing methods were changed, so upgrade is automatic
* limited campaignSendTest() to a total of 25 sends due to abuse.
* added pseudo transactional campaign support - see docs for campaignCreate()
* added campaignEmailStatsAIMAll(), which is just like campaignEmailStatsAIM() except it allows you 
to pull bulk stat history on all of the members who received a campaign. Note the paging options.
* added campaignEcommAddOrder() beta function. Not fully documented or intended for mass consumption.

2008-09-15 (Mon, 9 Sep 2008)
* Permanently closed security hole across all active API accounts. Logging in with old User Id is 
no longer supported.
  Check the login() and apikeys()/apikeyAdd() functions for more information.

2008-08-08 (Fri, 8 Aug 2008)
* MailChimp API v.1.1.0 release 

    - does not require an upgrade to 1.1
    - the method is a quick, one time fix for your account
    - any new API users will not be affected

* Significant changes to be aware of when upgrading to v1.1
    - The campaignCreate() method was completely overhauled and changed from the initial 1.0 
      version released. Read the docs on it before making the jump
    - API Keys were introduced. 
        - If you login() everytime and use the Key returned by login(), this will not affect you
        - If you have hardcoded the previous API Key returned, it will no longer work. We are 
          not backporting this and will not make old API Keys work with v.1.1
    - Error Codes/Messages were revamped. What you have now *should* work, but the recommended way
      now will be to check the numerical code we return and act on it
