[Issue 19]

I rewrote my code for detail result which is now definitely proper. 
I reorganized a little bit some code which was not in the right place and added few comments. 
I also adapted solving questions screen for i18n. 
Don't forget to fetch the node server.
The presentation of both screens is acceptable now.
We have new key/values in strings.xml so we will need Junko to update the japanese xml.
I already did the same for french.
