This adds tracking of other build types and their exit status and
allows us to use desktop notification for these also. Also cleaned
up some unnecessary cleanup code.
This patch adds tracking of the build process's status code. This allows us
to respond to the build process within the program much easier. Also added
a simple API for desktop notification of the build process and its exit code
which is useful and pretty.
Summary: Also add some uses of this method on scm stash and file deletion.
