When there are more than 2 countries, just list "n countries"

Users were having problems when they looked up things like "English"
and were presented with "United Arab Emirates" and such, as these
colonial languages are spoken in so many countries.
So this just displays the number of countries.

Add Wasta 14 (Cinnamon) keyboard handling via IBus alone

When IBus is used in Wasta 14, it becomes the sole keyboard handler.
(Wasta 14 is based on Mint 17 using Cinnamon.)
The IBus settings list both XKB and IBus keyboards together, and the
IBus code  handles switching keyboards the same way for both.
Cleanup after review

- Added a lazy-load trick to make first page come up faster
- Make wait cursor stay until load complete (not entirely successful)
- Added a unit test as another way of trying the gecko version
- reduce the white space between images
- improve some comments
