[evolution-patches] patch for using timezones in the http calendar backend

[Rodrigo Moya <rodrigo novell com>]

As someone mentioned on the evo list, the webcal backend is not using
correctly the timezones it gets from the remote ical file. This patch
fixes that. It is for HEAD and 2.0.x, where it should be fixed also.
