For issue 6195

To fix issue 6195, setting the REQUEST_URI in a cookie before refreshing the page (for IE8 in html5 mode), and remove the cookie after the refresh is done.

What has been done:
- adding pathInCookie (bool) to add the REQUEST_URI in a cookie to not loose it after refresh (IE8 in html5 mode) and pathInCookieName (string) to specify the name of the cookie. Default will be "angular"

If anybody can help me to create testing case for this pull request that would be awesome
