next steps and analysis links for claims

card related_articles with codename related_articles has to be created 

use {{+related articles}} to add the analysis links to a claim view

additional css used at the moment:

```css
.analysis-link a.company,a.topic {
padding: 2px 3px !important;
border-radius: 3px;
font-size: 0.9em;
color: #fff;
text-decoration: none;
}

.analysis-link a.company {
background: $claim-tag-companybg;
&:hover{
background: $claim-tag-companybg-hover;
}
}
.analysis-link a.topic {
background:  $claim-tag-topicbg;
&:hover{
background: $claim-tag-topicbg-hover;
}
}
```
this needs a decent "close button" instead of the "X" and the javascript for hidding this has to be written
