IE7/IE6 fix concerning localStorage.

localStorage is not available in IE6/IE7, and it seems that even
referencing the localStorage variable causes both of the browsers to
shut down everything.
IE 'unsafe:' fixes, removal of whitespace.

Some combination of IE/AngularJS marks relative URLs safe, so the
angular compiler has to be told that relative URLs are okay.
ISO compatibility for IE8. Some whitespace changes.
More IE8 ISO/Date fixes.

This one is for the validDate filter, which is used in a couple of
places. Did the same ISO parsing date fix as before.
