Fix check for SSLCertificateFile, SSLCertificateKeyFile variables in vhosts/standard.tmpl, now using dict.get()

If the DocumentRoot value wasn't set, applying the state would cause the
following error:

          ID: site.example.com-documentroot
    Function: file.directory
        Name: None
      Result: False
     Comment: Specified file None is not an absolute path

     Changes:

This fixes the problem by not trying to check for the DocumentRoot directory is
the value is missing.

Make sure that you can makedirs incase parent folders are not created

Create the vhost DocumentRoot directory if it does not exist

Replace require_all with use_require in map.jinja, we want to be able
to use custom Require values.

Remove uneeded Directory in standard.tmpl and add conditional and
default value for Require.

Fix bad filenames in standard.sls
