Display more exact build info

[eunikolsky]

You can check the current SDK and sampler app version in the settings. It would be more useful to include some extra information there, such as git commit hash and build time. Eg, SDK Version: 1.5.0 (abc123de; Wed Feb 4 16:10:19 PST 2015). This will help with debugging and troubleshooting.
