ui: delete action functions
The handling of actions is done without taking care of the return value which
make it impossible to detect UI elements since it's a immediate mode like
implementation.
Users are encouraged to write code like instead:
```
if (button_handle(&b, &ev)) {
// Do something.
}
```
