find and kill process by window title

[Gintaras]

Using just title can be dangerous. It could find and kill some other process. Therefore I also added class in the example. Also you can add program name.

int w1 = win("*name" "" "" 1) ;;dangerous
int w1 = win("*name" "class" "" 1) ;;ok
int w1 = win("*name" "" "program" 1) ;;ok
int w1 = win("*name" "class" "program" 1) ;;ok, this is the safest
