[Improvement] Make search function "suggesting"

[Wikinaut]

Make search function suggests as you type (after entering 2 or 3 characters).

@segler-alex @werman can you? I really wish like to see this implemented.

@Wikinaut I definitely can implement this, but I don't have the time for it as for now. Anyway I can help if you are willing to implement it.

There is a lot to improve in the search like narrowing search by tags, bitrate, country, ... However quick suggestions will be a good start.

Some details I have thought of:

• Results should be displayed even if one character is typed but from local station lists (to reduce requests amount).
• When there is a small number of suggestions or query is like 3 - 4 characters long - make a search request.
• Search request is forced if user presses a search button.
• N last search results should be cached to reduce requests amount and improve responsiveness.

Implementation idea:

• recycle (use) code from the Wikipedia App https://github.com/wikimedia/apps-android-wikipedia , most likely from https://github.com/wikimedia/apps-android-wikipedia/tree/master/app/src/main/java/org/wikipedia/search

• Soll ich mich hier ranwagen, oder kann es einer von Euch machen ?
• Would prefer if someone of you can implement that in the near future.
