Fixed A LOT of bugs.

- Our common activity ASMApplication wasn't declared on the manifest.  Then, inside, we weren't using the model anymore, so we deleted it.
- After this, the method "isFirstTimeRunning" didn't need to catch any context.
- We've created another method in our DAO to select a City from its ID. That way, we only have to catch the ID of the city to show it on our CityActivity.
- The intent from the MainActivity was sending the CityActivity the position, instead of the ID, and so the first object that it was trying to get had index "0", which isn't valid.
- Our CityActivity now shows every property of a City, including its condition.
- Big mistake on the "insert" method of our DAO.
