[openstreetmap/openstreetmap-website] Simplify user links (#1785)

[Andy Allan]

Currently our views are full of very verbose links to users, for example:

> link_to contact.display_name, :controller => 'user', :action => 'view',  :display_name => contact.display_name

This can be simplified by using the "user_path" method, to something like

> link_to contact.display_name, user_path(contact.display_name)

Normally this could be made even easier, since rails does the right thing with `model_path(model)` by default. However, since we use the `display_name` in the url rather than the `id`, we first need to define `to_param` on the User model:

```
def to_param
  display_name
end
```
This then allows the links to be even more straightforward, namely:

> link_to contact.display_name, user_path(contact)
