(Partial/merge of upstream 9247134eaba9a1d0fa74f22de238af1476663005, 1a3f0da9229a8e524d1010cdc8bd3b9da71fe529, and 3e343522226e6c249f5cb05436eec347b87c6361)

- use wildcard for TRANSLATIONS in bitcoin-qt.pro to automatically build all translations present in src/qt/locale (thanks @tcatm)
- first load translations/<language>.qm, then translations/<language>_<TERRITORY>.qm, so that territory-specific translations take precedence, but the fallback is on the base language if no territory-specific translation exists.
Now it can't be told if this is was a Windows App before. All Mac design principles are fulfilled and some cosmetics have been applied to suit the native look and feel. The biggest change there is the proper use of the Dock icon which takes the role of the Tray icon on Mac.
The QDoubleSpinBox improves entering of Bitcoin amounts, no two separate fields are required anymore. All functionality and validation effects have been retained; pressing the comma key will be internally translated to a period to keep it consistent throughout the application and eases entering in countries which use the comma as decimal separator.
Additionally, Notificator now supports Growl, Mac's native notification system. This is provided via Apple Script in order to avoid linking to Growl on compile time. Other changes involve encapsulation of Toolbar and Menubar creation, loading of Qt's own translation and some clean up.
