#KT-1388 Fixed

KT-1694 Java vararg override, Why is it intuitive interface?

#KT-1694 Fixed

Removed test for KT-1666, since navigation to standard libraries is working normally now (instead of navigation to the same source).

Added test checking that StandardLibraryReferenceResolver returns not null for all members of jet namespace.

Replaced jet.Tuple0 with Unit in rendered descriptors. DescriptorRenderer cannot detect fake Tuple0 as Unit.

Their numbers now start from 1. This is made for consistency with auto-generated sources for these types. Parameters of runtime types (written in Java) are numbered starting with 0, too.

 #KT-1970 Fixed

KT-1894 Do not suggest "trait" after fun
 #KT-1950 fixed
 #KT-1894 fixed

Renamed "std" library containing Any, Nothing, tuple and function types to "jet.src" and added readme file.

 #KT-1069 fixed

Moved *.jet.src to separate directory and renamed to them to *.jet. Thus, they will be correctly loadable via PSI.
