Add shortcuts for frequent phrases in documentation

[Hsilgos]

The most often construction in our documentation looks like: {@Java Interface}{@Swift Protocol}{@Dart Abstract class}. We repeat it for many classes and actually it contains an error, because it must include {@Cpp Abstract class}. The idea is at least to use shortcut for such case, something like {@Shortcut interface} (or {@Shortcut Interface} when capital letter is necessary).
This idea might be extended to use externally provided file with shortrcuts
