[evolution-patches] [Calendar ][Backend]Fix for bug 332276, support getting weather data through proxy

[jeff cai <Jeff Cai Sun COM>]

Hi,
Calendar weather data will be retrieved by libsoup in http protocol.
But it doesn't support getting data through proxy now.
The patch does the following work:
When a new soup session is created, read system proxy configuration
 read and set a proxy on the soup session.

Jeff
