latest git commit -- missing files and bad java version

[Ross Duncan]

Hi guys,

Just tried to build the latest quanto, and the front end does not compile, looks like the jython jar is missing. See bottom of this message.

After putting jython 2.7.0 in some plausible place it compiles with several warnings, and promptly falls over on launch, bad java version. What JDK is required to run it? I have java version “1.7.0_45”.

52 means java 1.8. The latest version of akka, which quanto uses for its concurrency depends on it. I've also now added jython to the repo.
