Title: HelperSet.prototype.formFor can now work without a block

formFor can now be used without passing a block (since some view engines don't support blocks):

```jade
- var f = formFor(resource, {})
= f.begin()
= f.submit()
= f.end()
```

Therefor, I created `HelperSet.prototype.form_tag_begin` and `HelperSet.prototype.form_tag_end`.

`form_tag_begin` returns buffer (since we have multiple lines to render there) so we need to concatenate the render buffer and the buffer returned by the function. See lines 289-292 in helpers.js.
