log-rework and iCloud fix

sorry, this got entagled a bit..
good news is: it is now much easier to test the caldav.js part
on the xml output, so we don't really require the server-backend
for testing.
Will add a test-node.js script in next commit.
test script for iCloud folder listing
switched on logging for iCal issues again.
