first testing commit

feedImageService has been mostly commented out after iOS7 branch update
last test on currentFeedProviderService still needs to be fixed
A couple others involving sorting seem to be failing now
second save

'fixed' most commented out tests
whatever is left commented is due to instance variables
  that would have to be made into properties
third commit

added one more singleton clear to service base tests class teardown
all tests passing

moved current user nil to setup instead of tear down
Update date test to not use compare
force time zone
Merge in testing
