Fixed bug when installing from the command line.
We forgot to set default values when installing from the command line.
Installing from the GUI worked.
Thanks Paul Spause.

Allow configuring output file truncation.
A new checkbox in the GUI allows specifying that stdout and stderr
should be truncated rather than appended. The registry must still
be used to set different disposition for each or to control the
disposition of stdin.

Fixed environment when no newline was present.
If the user entered environment variables without a trailing newline we
might have been left with only one trailing NULL and therefore the
environment parameter would have been invalid. The path of least
resistance is to add two trailing NULLs unconditionally.

Fix initial focus.
Ensure that the service name field has the initial input focus. It
already did for the install dialogue but didn't in the remove dialogue.

Ensure CRLF is removed from GUI strings.
Windows 2000 will show funny characters where a string formatted with
message_string() contained a CRLF. Explicitly add NULL to the end of
the strings so that they are shown correctly on Windows 2000.

Compiler food.
Make strip_basename() non-static so it can be used elsewhere,
particularly in cases where int and size_t are different sizes, ie on
32-bit builds.

Set environment from the GUI at install time.
Added an extra Environment tab to set a newline-separated list of
environment variables to replace or be added to the service environment.
Input is validated by relaunching nssm itself with the proposed
environment set.

Allow appending to the service environment.
The new registry value AppEnvironmentExtra allows defining a list of
environment variables which will be appended to the environment, as
opposed to those defined by the srvany-compatible AppEnvironment, which
replaces the environment.
Though it would serve no useful purpose beyond verifying whether or not
I went to the effort of writing a code path for it, it is possible to
define bother lists and have them behave intuitively.

GUI overhaul.
We now have a much less sucky GUI with tabs, combo boxes and all sorts
of whizzbang stuff.
The new GUI allows setting most of the advanced features we support
directly from the service installer without having to poke about in the
registry.

Pass parameters around in a data structure.
Instead of static variables and functions taking a dozen arguments we
now use a single data structure, nssm_service_t, for the service.
The code is easier to read and understand, especially when adding more
variables through to functions.

Enforce maximum report delay when starting service.
We were not changing the service's state to running until the restart
throttling threshold had passed. However best practice is to change the
status to running or stopped as quickly as possible. Therefore we we
now report the status after no more than 20000 milliseconds regardless
of the throttle setting.

Don't automatically close the GUI on error.
If a parameter in the GUI was missing or invalid we were closing the
dialogue and forcing the user to relaunch the installer/remover.
Instead we now loop until the service has successfully been
installed/removed or the user cancelled the operation.

Spawn a separate thread for stop_service().
We must acknowledge a STOP or SHUTDOWN control promptly but the
termination of the application may take a significant amount of time if
one of the AppStopMethod* registry values is set.
We now spawn a separate thread to try to stop the process and to call
await_shutdown() while the main thread immediately acknowledges receipt
of the STOP request. Once the worker thread has updated the service
status to say that application is really stopped we will be
automatically cleaned up by the system.
If for some reason we can't spawn a new thread we log an error and
ignore user-supplied timeouts so as to ensure we tidy up promptly.
