Handles update checking for Backdrop core and contributed projects.

The module checks for available updates of Backdrop core and any installed contributed modules, themes, and layouts. It warns site administrators if newer releases are available via the system status report (admin/reports/status), the module, theme and layout pages, and optionally via e-mail.
