- Added more modules and configuration options
 - Renamed sls files to reflect what they do.
 - added mpm options for Debian

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

Add optional templating for the register site aspect of a pillar.

User can specify keys to be included as defaults, otherwise it is
treated as a normal managed file.

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.

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.

Fix typo: `user_require` -> `use_require`

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

- Adding confext to virtualhost names.
- Renaming the default config file for Ubuntu (000-default.conf).
- Adding ability to use "Require all granted".
