Installer does not check for an existing installation

[GoogleCodeExporter]

If you run the installer twice it attempts to install a new copy over the
top of the existing one.

If the service is running this will fail since it can't overwrite the
executing exe, otherwise it silently overwrite the existing install.

I'm not sure what should happen. Probably it should check for an existing
install, and if there is one offer to uninstall it first before attempting
to install again.

Added a check for a previous version, which asks the user to uninstall (we 
can't do
this automatically as we don't necessarily know where it was installed).
