m2crypto beta release

I did some quick QA on the beta release of m2crypto, I found a few 
problems but overall I think the quality of the project has improved 
significantly over the last few months.

1. test_ssl.py is not working for me. The problem is the unittests for 
the SSLClientTestCase. All of these tests fail with a Connection refused 
error. I haven't looked into
this any deeper than this, because I'm just doing some preliminary 
checks right now. The rest of the unittests work flawlessly for me.

2. There still are a bunch of compiler warnings. These just need to go 
away before the final release. I've noticed that SWIG-1.3.24 generates 
code that
produces compiler warnings, these warnings go away in SWIG 1.3.25. I 
know I suggested that we should make 1.3.24 a requirement, but I would 
say that we should
probably just require 1.3.25. We should have a simple check in the 
setup.py script to ensure that we are using an appropriate version of 
SWIG. Below you'll find the
compiler warnings that we need to get rid of.

3. I ran valgrind on all of the unittest files except, test_ssl, 
test_ssl_win, and alltests, I found some leaks in test_x509, but I 
suspect that it is the issue is how the tests are
written, and not any underlying problem in the toolkit. Below you'll 
find the valgrind output

This is just a cursory ananlysis of the beta release.

Cheers,
Matt Rodriguez

Here is the valgrind output.
