- remember me cookie security improvement (the time when the cookie was generated is saved and checked in range [now-remember_me_length; now]

- tags improvements
 * pass to templates all fields in table #tags (handy for plugins such as type tags)
 * fix issue with tag letter when first letter is accentuated (utf-8)
 * tags are sorted on url_name instead of name (accentuated first letter chars are the same as without accent)
 * better use of columns in by letter display mode
