Fixed crash when stopping the service.
NSSM tidies up by looking for processes whose parent PID matches the PID
of the monitored application. Because process IDs are reused, however,
it's possible for NSSM to kill a process which was not a child of the
monitored application if that process had a now-exited parent process
whose PID was reused. On UNIX the PPID would show as 1 for an orphaned
process but under Windows, at least when querying a process with the
Toolhelp32 toolkit, we see the original PPID of the process even if the
parent is no longer running. Thus it is not sufficient to compare
parent PIDs when checking if a process was launched by our application.

a bluescreen.

Handle missing registry values.
Warn if AppParameters is missing.
Warn if AppDirectory is missing or unset and choose a fallback directory.
First try to find the parent directory of the application. If that
fails, eg because the application path is just "notepad" or something,
expand %SYSTEMROOT%. If THAT fails it's time to give up and go home.
Thanks Arve Knudsen.

Kill process tree when stopping service.
Ensure that all child processes of the monitored application are
killed when the service stops by recursing through all running
processes and terminating those whose parent is the application

Don't suicide on exit status 0.
Suiciding when the application exits 0 will cause recovery actions to be
taken. Usually this is inappropriate. Only suicide if there is an
explicit AppExit value for 0 in the registry.
Technically such behaviour could be abused to do something like run a
script after successful completion of a service but in most cases a
suicide is undesirable when no actual failure occurred.

Handle startup failure.
Don't hang if startup parameters couldn't be determined.
Instead, signal that the service entered the STOPPED state.

Ensure systems recovery actions can happen.
In Windows versions earlier than Vista the service manager would only
consider a service failed (and hence eligible for recovery action) if
the service exited without setting its state to SERVICE_STOPPED, even if
it signalled an error exit code.
In Vista and later the service manager can be configured to treat a
graceful shutdown with error code as a failure but this is not the
default behaviour.
Try to configure the service manager to use the new behaviour when
starting the service so users who set AppExit to Exit can use recovery
actions as expected.
Also recognise the new AppExit option Suicide for use on pre-Vista
systems. When AppExit is Suicide don't stop the service but exit
inelegantly, which should be seen as a failure.

Fix path lengths.
Some buffers were being limited to MAX_PATH characters when higher
limits were more appropriate.
For example the maximum length of a command line is documented as 32768
characters with the application name part limited to MAX_PATH.
Long applications paths and arguments could be truncated when written to
the registry.

Decide how to handle application exit.
When the service exits with exit code n look in
HKLM\SYSTEM\CurrentControlSet\Services\<service>\Parameters\AppExit\<n>,
falling back to the unnamed value if no such code is listed. Parse the
(string) value of this entry as follows:
Restart: Start the application again (NSSM default).
Ignore: Do nothing (srvany default).
Exit: Stop the service.
