Animated Weather Widget almost done #2

Updated main screen now, with drop own chooser when the user has weather for multiple cities, now showing a country flag for each location. 

Swipe back and forth between cities. 

Moved the Settings and Refresh into an Action Bar rather than on the main screen.

Location settings now streamlined and easier to use, including city text search facility:

Sorted out all Landscape/Portrait issues. 

Linked main screen to launcher icon. 

Final screen needed when user hits Launcher icon but has not yet added widgets for any location, need to show an example of drag and dropping widgets so they get the idea of what is required. 

Then lots of testing...
