Don't fail on missing DocumentRoot

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
     Started: 15:07:05.596723
    Duration: 4.929 ms
     Changes:

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

Update standard.sls

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

Create the vhost DocumentRoot directory if it does not exist

Add optional templating to register_site files

Issue#41 configure multi proxypass configuration in vhost
Thank you!

This is more reliable than version numbers which might change with point
releases (in particular for Debian Jessie) and is more likely to not
conflict between multiple OS.

Fix case where state != enabled causes error

When using the register_site state, if the `state` for the
site in the apache pillar did not equal "enabled" the error

```
Cannot extend ID 'a2ensite <name>' in 'base:apache.register_site'. It is not part of the high state.
```

If statements were there to build out the `a2ensite` or `a2dissite` ID
appropiately, but the next state for managing the config always
assumed that the `a2ensite` id would be there.

Addressed by making a Jinja variable that will be the appropiate ID,
probably could use a better name.
