ENH: Show build information in Windows shortcut names for nightly builds
Created by: msmolens
Previously, multiple installations of nightly builds would result in indistinguishable shortcuts named "Slicer" on the Windows 8 start screen/Windows 10 start menu. This commit adds the build information to the shortcut name for nightly builds. Released builds will still show "Slicer".
An example of a nightly build shortcut name is now:
Slicer 4.4.0-2015-09-24
Fixes #2702 Fixes #2829
