it conflicts with the compilation on daemon, so transistion should
be planned accordingly, and now it is not a good time for it.
The most important part of the renaming remains intact.
Partially reverts commit "Rename scripting libs and plugin - invert embeddable suffix"
now regular, unshaded libs, are named with suffix `-unshaded`, while
former `-embeddable` ones named without any suffix. This will encoursge
use of the shaded libs by default, avoiding conflicts with 3-party
libs packed into the `kotlin-compiler`.
Note, that only the "frontline" libs are renamed to avoid switching
problems, the ones that not normally used directly are left as is,
including the `kotlin-compiler` itself.
- implement error result
- refactor other result classes
- implement handling in the script evaluation extension - also restores
previous script error reporting functionality
- add possibility to customize result fileds in script and REPL
- refactor result calculation in the backend: cleanup, rename (since
it is not only about REPL now)
