#322 rename app, remove most entries of the word 'alphabet'

Solves a part of #322 (further actions are required, e.g. changing the displayed name and description on Google Play)

What is the purpose of the name change? I see no apps on the Google Play that are named that way.

@winter-yuki Sorry, I ought to have explained this. Thought that you'd seen the issue and had no questions.
Anyway, it's a good habit to log reasons for things, so I'll do it.

VN said that, although less ugly than "Braille Language", the term "Braille ABC" is not habitual to the ear of a Russian braillist. She consulted with others (teachers as well as students), and they worked out this title.

When I've first heard it, my internal reaction was much like yours: I did not see much purpose, and, besides, people might get confused. Though later I started to think that probably she is right - we do not want our app title to sound unfamiliar and strange to end-users (even in the slightest), do we?
On Google Play, I shall leave the double name so that the app is searchable by the old title.

I've discussed the matter with Anna D. She does not object ("if the client wishes it, then be it").

Uf. Double name is twice more confusing. Looks like something not necessary and astonishing. But ok, if there is some consensus here and it is not only the VN opinion.
