fixing throwing exception in IE11 metro mode

Hi,
localStorage doesnt work in IE11 metro mode and probably is not working in lower version (metro mode). Seems to be there is big differences between IE desktop and metro mode in W8. If you wanna try access to localStorage there, throw you exception and your app collapse. Its really weird, i couldnt find any solution. So i add try/catch block to protect app collapse and generated new compiled version. Works fine, if app throw exception just send error to $log and you can work still work with $storage object normally.
