Request: make stagefile configurable

[dsielert]

remco doesn't seem to like my .env configuration files as the stagefilename is the dest prepended with a '.'
Workaround for now I found that works is to use

 reload_cmd  = "cp /var/www/env /var/www/.env

The stageFileName is always ioutil.TempFile(filepath.Dir(s.Dst), "."+filepath.Base(s.Dst)) at the moment.

So if your destination file ist /var/www/env then your stageFile would be /var/www/.env.7643745 (something random).

You can then use this stageFile in your check_cmd like this:
check_cmd(string, optional):
The command to check config. Use {{.src}} to reference the rendered source template.

{{.src}} is the stageFile.

You can't use it that way? Do you have an example where you need a different behavior?
