Feature/add search service

[StRhys]

What

This adds an extra service option for search

A couple assumptions about radio behaviours

• if a service is given, eg /feedback?service=search, then that service radio should be the default one checked
• then if this is the case the "specific page" input box should be blank

If this isn't the expected behaviour I can change it to only do it when search is given as a service

How to review

Run the feedback controller
Goto http://localhost:25200/feedback?service=search
Check if extra option is there
