Hamlcoffee options

This lets you override the hamlcoffee compiler options from the stefon settings.

It also makes the escapeHtml and the escapeAttributes settings true by default.

This is the safer setting that hamlcoffee uses by default. An example:

```haml
= "<a href='#'>test link</a>"
!= "<a href='#'>test link</a>"
```

becomes
```html
&lt;a href=&#39;#&#39;&gt;test link&lt;&#47;a&gt;
<a href='#'>test link</a>
```

Notice that the exclamation mark lets you use unescaped html.
