Use non-ABI jars for kotlin compilation. (#41)

* Use non-ABI jars for kotlin compilation.

Adds two new kotlin_compile attributes:
1. verbose: for printing debugging info
2. args: for passing arbitrary args to compilation

Adds new test from @jmmk re: tornadofx

* Exclude jars if basename starts with "kotlin-"

Slightly less naive attempt at excluding kotlin stdlib jars.

* Remove jar name exclusion
