Move resources from /src to separate /resources directory.

Previously this files was stored in /src directory and was included in
resources mainly by SourceSet.projectDefault from sourceSets.kt:

val processResources = tasks.getByName(processResourcesTaskName) as ProcessResources
processResources.from("resources") { include("**") }
processResources.from("src") { include("META-INF/**", "**/*.properties") }

Also there are some custom rules like this:

resources.srcDir("../idea-analysis/src").apply { include("**/*.properties") }
resources.srcDirs("idea-repl/src").apply { include("META-INF/**") }

All this rules are synthesized in script
https://github.com/snrostov/kotlin-migrate-resources/blob/master/src/main/kotlin/main.kt

This commit created using that script. See README.md for more details on
 script.
