Added Polyglot and Scholastical Russian keyboard layout

I have exerted myself to create a new keyboard layout as I have had the desire to write Russian in pre-1918 spelling as well as Serbian with the same layout. I have not missed the opportunity to map almost everything else contained in Unicode for Cyrillic to it while still keeping it usable tantamount to the rest of the layouts. Only some superseded signs used until the 1920s for Abkhazian and some signs which would also have a place in the Compose table (Ԕ ԕ Ԗ ԗ Ԙ ԙ Ԫ ԫ ꚅ Ꚅ) or obviously replaceable signs (and of course yet unencoded glyphs) had to be left out. Of course there is much explicit Unicode with such an approach. The principle has been to look up where the characters available are used or how long and often if they aren’t used anymore and give those of the most used languages and those most often used in history or in scholarly editions the most favourable positions. Before a special Cyrillic layout for an indigenous language of the Russian Federation is created, most likely this layout may serve at least for occasional use of the exotic language. For many of the rarer languages the mere inclusion is a benefit and the most urgent exigencies consisting in a character not being available with any layout are soothed. If linguists who intend to write Cyrillic are not inclined to be creative enough to invent new glyphs, the linguists shall be utterly served with the unique glyphs and combining characters included in this layout.
