Title: Support for additional keywords lists and vocabulary attribute.

After converting an old style wms configuration to a new theme based configuration, I discovered that the vocabulary attribute was missing in the WMS Capabilities. Also missing where additional keywords lists.

This patch adds support for both missing features to the theme writer classes.

Fragment of original configuration:
```xml

behoud
milieu
landbouw
natuurbescherming

Beschermde gebieden

```
Corresponding fragment of new configuration:
```xml

behoud
milieu
landbouw
natuurbescherming

Beschermde gebieden

```
Expected capabilities output:
```xml

behoud
milieu
landbouw
natuurbescherming
Beschermde gebieden

```
But was instead:
```xml

behoud
milieu
landbouw
natuurbescherming

```
