Title: Added support for specifying the ca-certificates.crt file

Added support for specifying the location of the ca-certificates.crt file.

To specify the location, use the configure() method before making any
async HTTP calls, like this:

from tornado.httpclient import AsyncHTTPClient
AsyncHTTPClient.configure("tornado.simple_httpclient.SimpleAsyncHTTPClient",
ca_certs='/path/to/ca-certificates.crt')

The file can be found in the tornado/ directory inside the source tree
distribution.
