initial lambda push; the current prototype suuports the following features:
*) function types syntax (optionally enabled with -XDallowFunctionTypes)
*) function types subtyping
*) full support for lambda expression of type 1 and 2
*) inference of thrown types/return type in a lambda
*) lambda conversion using rules specified in v0.1.5 draft
*) support references to 'this' (both explicit and implicit)
*) translation using method handles

The modified script build of the langtools repository now generates an additional jarfile called javacrt.jar which contains an helper class to be used during SAM conversion; after the build, the generated scripts javac/java will take care of automatically setting up the required dependencies so that code containing lambda expressions can be compiled and executed.
