struct widget *  new_widget,
struct widget *  add_dock,
bool  dir,
Sint16  start_x,
Sint16  start_y 
)

Add new widget to scrolled list and set draw position of all changed widgets. dir : TRUE - upper add => add_dock->next = new_widget. FALSE - down add => add_dock->prev = new_widget. start_x, start_y - positions of first seen widget (active_widget_list). dlg->scroll ( scrollbar ) must exist. It isn't full secure to multi widget list.
