Quiz: add support for Buddies quiz

[mvysny]

I have got a question about two awesome features in it. The "buddy" and the
"junctures" functions.
Is it possible to make a stand-alone app (of course with costs) with these
two functions in a flashcard-like app? I would really appreciate it (and I
am 100% not alone).

For example:
I give the information that I know the Kanjis 食 and 事. After that, the app
should ask me about the Kanji alone AND about the combinations. That means
the reading AND meaning of 食事 (しょくじ -> meal). If i add another Kanji
like 物 the app should ask me about 食べ物. And so on.

This is a great idea! This would definitely help learners learn the readings used in different words. Yet, instead of having a specialized app for this, I'm thinking of make this built-in into Aedict3, free of charge of course ;)
A new Quiz if you will. The new Quiz could work like this:

One example, the new functionality could work as follows: open the Kanji Search, find several Kanjis and then just press a new Buddy Quiz button which will quiz you from the buddy words.
Also, when this is implemented, you could be able to multi-select two or more kanjis in your Notepad and launch the Buddy Quiz from those kanjis.

This may be very powerful when combined with the different quiz types which are already present in Aedict: guess readings from kanji, or guess kanji from readings, and other quiz types.

Even better, instead of showing a Buddy Quiz, Aedict could show the list of words containing both kanjis. Then, you can simply launch the Quiz itself, my long-touching any item, selecting the "Select All" button and then selecting "Quiz" from the upper-right menu. This will avoid overcomplication of the UI by adding too much of the buttons.

Incidentally, this is exactly what the ScratchPad search button (the upper-right magnifier-glass button in the Kanji Search screen) does.

I will thus add the "Buddy Search" menu item, shown when at least one entry is selected.

As it turns out, there is a "Search in Dict" menu item, shown when kanji-only-lists are being selected, which actually performs the "Buddy Search" functionality.

Renamed to "Buddy Words" and applied to all lists of any entry type.

Fixed in Aedict 3.39.27.

Please use either the ScratchPad, or select any entry and press "Buddy Words" from the menu - this should list all Buddy Words. Now, select all items and press Quiz.
