Explicitly load the Logger class. (ActiveSupport 3 compatibility change.)

Under ActiveSupport 2.x, the Logger class was loaded before the
subclass defined in lib/casclient.rb was defined, and therefore things
worked out just fine.  Under ActiveSupport 3.x, said class is no longer
loaded merely by `require 'active_support'`.

There's probably a better way to adopt RubyCAS-Client's logging override
to ActiveSupport 3, but this method has an attractively low changed line
count.  It's enough to get parts of RubyCAS-Client to _load_ under
ActiveSupport 3.  However, I'm not yet sure if it's enough to get
RubyCAS-Client to _work_: that's a much bigger job.
