This adds a javac step to the KotlincToJarStepFactory. If any java files are found it will invoke javac, otherwise it won't do anything.
This also adds java annotations processors to kotlin library rules.
This also fixes an issue where the bootclasspath was not being set properly for kotlin rules.
For now, this only works if the java annotation processors do not reference kotlin code and the kotlin code does not rely on annotation processors.
This fixes #1037 (closed)
This probably isn't ready to merge yet until a stable version of kotlinc has support for passing java files directly to it. Currently you can use 1.1.3-eap-68 or newer to test this out.
