Added default shortcut Ctrl + I for change colors.

This should have the exact same of clicking the toolbox Settigs > Configure Okular > Accessibility > Change colors and then clicking Ok, therefore changing the saved configs.

I am not sure if:

- viewport()->update() is the right way to update the screen after this config change? Where is the `update()` method defined? If I tracked well, viewport() returns a DocumentViewport, which does not seem to have such a method.

- I placed the new feature in the right class

but it seems to work.
