1. Prepare Pure and Bell specific `Application`
classes and add them to `app` target:
- `products/BellHybrid/apps/Application.cpp`
- `products/PurePhone/apps/Application.cpp`
2. Update `CMakeLists.txt` files.
3. Move `ApplicationBell` implementation to Bell-specific
`Application` class and remove `ApplicationBell` files.
4. Change Bell apps parent classes from `ApplicationBell`
to Bell-specific `Application` class.
5. Rename `Application` to `ApplicationCommon` in the rest of the files.
Created separate cmake library, defined public and private
include search path and dependencies, removed this app
from BellHybrid target dependencies and added explicitly
as PurePhone dependency, cleaned up include paths
Due to vfs deprecation there is need to remove all vfs calls from code. This PR covers module gui. There are some modifications in other modules included which are necessary because of build system issues.
Change filename of internationalization files from i18 to i18n.
I18n should stand for internationalization, not i18. That's why I changed in 'module-utils' name of the folder 'i18' and both .cpp and .hpp files to 'i18n'.
