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:

This folder contains lint scripts.

check-doc.py

Check for missing documentation of command line options.

commit-script-check.sh

Verification of scripted diffs. Scripted diffs are only assumed to run on the latest LTS release of Ubuntu. Running them on other operating systems might require installing GNU tools, such as GNU sed.

git-subtree-check.sh

Run this script from the root of the repository to verify that a subtree matches the contents of the commit it claims to have been updated to.

To use, make sure that you have fetched the upstream repository branch in which the subtree is maintained:

Usage: git-subtree-check.sh DIR (COMMIT)

COMMIT may be omitted, in which case HEAD is used.

lint-all.sh

Calls other scripts with the lint- prefix.
