Blocks without filters

I've added optional arguments which help out when you need the raw block content. This is useful if you're not using the WYSIWYG editor or want to apply your own filters.

```
the_block($name, array('apply_filters' => false));
get_the_block($name, array('apply_filters' => false);
```

This is not backwards compatible with defining the type of editor and will require changing your code to -

```
the_block($name, array('type' => 'one-liner'));
get_the_block($name, array('type' => 'one-liner');
```

Or combine both -

```
the_block($name, array('type' => 'one-liner','apply_filters' => false));
get_the_block($name, array('type' => 'one-liner','apply_filters' => false);
```
