hacked slow sync now produces proper output

Before the output of item statistics only existed for the refresh sync
(which is not sooo interesting), but now it also outputs the stats from
the first sync.
slow sync output improved.
no adds on faked slow sync, method never gets overwritten

in datastore never overwrite sync method. Method now only gets
overwritten temporarly in another field. So the datastore should always
keep what the user did set.
added idle service calls to prevent premature kill of service

sometimes the service got killed, when not triggered by app. I guess I
would need to adopt the activity or so... I have no clue. Now just
trigger service calls. Bam.
removed some logging.
repaired idle assistant.
repaired idle and memory function in serviceHelper
2013-06-18 => 0.1.31

- service could get killed before sync did finish. Hope to have a fix
for that now.
- service periodically prints out its memory usage to the log, now.
- slow sync hack now outputs item statistics for first sync, too.
