Two things, plus cleanup

First, moves the wp_remote_get inside the get_transient else, so that we only pull from google calendar if valid cached data isn't available.

Second, modifies line 338 of class-gce-display.php so that a currently-running event is displayed when showing a list view limited by number of events.  (I imagine the most common use case here is an "Upcoming events" type list, so should include current.)

Third, a bit of random code cleanup.
