fixed: UGContainer<Type> used a std::vector<Type> and when a new item was inserted

then current iterators (and pointers) were invalidated
         now we are using std::vector<Type*>
         this caused some crashes when a new user was added by 'adduser' winix function
added:   plugin 'export' is able to upload files on a remote server now
         (not finished yet)
changed: Thumb class is now called: Image
         and we are able to resize images too
         (some new options in the config and in mount points)
added:   some new plugin messages
