README

Source code of this module is copy-pasted from https://github.com/JetBrains/intellij-community/tree/master/plugins/kotlin/common (not the whole module is copy-pasted but only parts which are required for scripting)

Copy-paste can be avoided by using artifact from https://redirector.kotlinlang.org/maven/kotlin-ide/org/jetbrains/kotlin/common/ but we decided that copy-pasting is more appropriate in this situation
