gui: change combiner for signals to optional_last_value
optional_last_value, which does not throw, has replaced optional_value as
boost's default combiner. Besides being better supported, it also doesn't
trigger gcc's -Wmaybe-unitialized warning, presumably because exceptions no
longer bubble-up out of signals:
```bash
boost/signals2/last_value.hpp:54:36: warning: '*((void*)& value +1)' may be used uninitialized in this function [-Wmaybe-uninitialized]
if(value) return value.get();
```
The change in default happened in Boost 1.39.0 (along with the
introduction of the signals 2 library. More information is available here:
https://www.boost.org/doc/libs/1_73_0/doc/html/signals2/rationale.html#id-1.3.36.9.4
