Title: Fixed "Rebuild project" IDEA command

For IDEA projects generated by sbt-idea plugin it is impossible to use "Rebuild project" command as it results in the following error message:
![Source files may exist in output paths](http://habrastorage.org/storage2/2cd/64a/023/2cd64a023382a4e428ef85b201bb61ac.png)
It is caused by IDEA bug: http://youtrack.jetbrains.com/issue/IDEA-81140.

The solution is to delete source folders from the build project module. Auto-completion for project files still works, so I found no downsides of this solution.
