Improve sbt-based IntelliJ integration in case of Windows

Use File.pathSeparator when processing classpath instead of just :
to don't end up with classpath like "C:\sth\a.jar:C:\sth\b.jar" what
was causing problems after split(":").

Display questions first and then wait for user input. I tested on 3
computes and without flush the printed questions were always displayed
just after user replied - never before.
