Title: css class generation improvements in ActiveAdmin::Views::TableFor

I had few issues with generation of css classes in th and td tags.
1) there was no possibility to use custom css class per column
now it can be used with :class option

```ruby
column :created_at , :class=>"datetime"
```

2) css class was empty if custom column title used

```ruby
column "My Custom Title", :title
```

3) for names with "_" (ex created_at, updated_at, etc) column had unexpected classes
example

```html
Created At
```

But

```html

```

was expected (you can see it even using demo http://demo.activeadmin.info/admin/customers)
