Bug1100916 answer a question helper

@Rik r?
I'm not saying we should merge those two files. I'm just saying that the current filenames are confusing because they don't convey how to use them.
By looking at the UX specs, I see four list of questions: homepage, suggestions when typing a question, my questions as a helpee and the helper view. Here's what I'm proposing:
```
           helper page    helpee page   home page
                   +            +           +    
                   |            |           |    
                   |            v           |    
suggestions        +---> list with day <----+    
      +                        +                 
      |                        |                 
      |                        |                 
      +-----> question <-------+                 
```
