Added C code instead of address call

Temporary address call in window_map.c:window_map_mouseup event is now replaced by reversed code
(Not sure why you've made a new pullrq, so I will repeat it here)
I think it would be more readable this way, with one indentation less:

```
case WIDX_PEOPLE_TAB:
case WIDX_RIDES_TAB:
    //code
default:
    break;
```
