moved checkResult routine into its own file

done that to allow test-scripts to work nicer..
do not report back a ctag if none was in the response

if server does not support ctags (or so?) and reported back
a 404 status, the service returned back an empty ctag
which could be "fulfilled" at some point, rendering it to
never update again... :(
add xml-thingie to calendar-etag report
removed unnecessary parameters
added node.js loadable Future library

it is the same as on device, but can be loaded easier from node.js
used in test scripts.
added ctag 404 response test script & data
added foundations xml-parser as loadable script
added https proxy test script
