- Solved some mistakes I did :
	- getQualifyingOfRace must return a List of race not a single race.
	- A class to encapsulate Qualifying is needed to avoid an awful return of List<List<Position>> (Only in getQualifyingOfRace2).
- Added year and round to queries (I miserably forgot it).
- New methods in JsonHandler to parse Standings data.
