More fixes for the App Engine support.
Added a new feature that allows you to supply your own provider for the CA_CERTS file. Just create a module named ca_certs_locater that has a method get() that returns the file location of the CA_CERTS file.
Lots of clean up of the code formatting to make it more consistent.

Keys are lowercase in a Response object, regardless of how Response object is constructed. Add control so that Authorization: headers aren't forwarded on a 3xx response by default. Set the reason correctly when running on App Engine. Patch from Alain Vongsouvanh. Reviewed in http://codereview.appspot.com/6422051/ Fix proxy socks for SSL connections. Fixes issue #199. You can now set httplib2.RETRIES to the number of retries before a request is considered to fail It is set to a default of 2 to mimic the traditional behavior of httplib2.
The following issues have been addressed:
223 HEAD requests fail calling the close() method of ResponseDict instance.
222 Can't disable cert validation in appengine

ProxyInfo objects now can construct themselves from environment variables commonly-used in Unix environments. By default, the Http class will construct a ProxyInfo instance based on these environment variables. To achieve the previous behavior, where environment variables are ignored, pass proxy_info=None to Http().

Issue 159: automatic detection of proxy configuration.
Issue 179: Allow unicode in proxy hostname.

The two major changes in this release are SSL Certificate checking and App Engine support. By default the certificates of an HTTPS connection are checked, but that can be disabled via disable_ssl_certificate_validation. The second change is that on App Engine there is a new connection object that utilizes the urlfetch capabilities on App Engine, including setting timeouts and validating certificates.
The following issues have been addressed:
Fixes issue 72. Always lowercase authorization header.
Fix issue 47. Redirects that become a GET should not have a body.
Fixes issue 19. Set Content-location on redirected HEAD requests
Fixes issue 139. Redirect with a GET on 302 regardless of the originating method.
Fixes issue 138. Handle unicode in headers when writing and retrieving cache entries. Who says headers have to be ASCII!
Add certificate validation. Work initially started by Christoph Kern.
Set a version number. Fixes issue # 135.
Sync to latest version of socks.py
Add gzip to the user-agent, in case we are making a request to an app engine project: http://code.google.com/appengine/kb/general.html#compression

Add default support for optimistic concurrency on PATCH requests
Fixes issue 126. IPv6 under various conditions would fail.
Fixes issue 131. Handle socket.timeout's that occur during send.
