 - Resolve packages to expression but not to files)

  #KT-1702 fixed

removed cruft from the API website generation and now have a separate JS API build (as it fails right now)

 #KT-1681 fixed

Added test for navigating to library sources when same function FQ name is defined in separate source files.

 #KT-1681 in progress

refactored the maven project structure so that things are in a simpler tree structure to avoid folks getting lost

enabled multiple source directories in the KotlinCompiler (we should refactor later to remove src - wanted to minimise breaking things first though :)

added an initial spike of a swing library for kotlin to help create swing UIs using nice kotlin builder syntax
