Display the language list on a separate screen instead of in a popup window

[sspanak]

• Each language is a SwitchCompatPreference.
• Add the country flag before the language name. The emoji code can be easily calculated from the country code. - not doing this because some languages are not associated with a country.
• In the summary display the English name, whether the dictionary is loaded, and the word count in kilo words. The lite version must also display the download size like this. Example: English (loaded), 171k words, 2.39Mb, or French, 350k words, 5.8 Mb. Potentially, use bold or italic to make it more distinguishable.
• On top there is a text field for searching. It can search by the native language name and by the English name. Placeholder: Ex. "Български", "Bulgarian", "العربية"...
