[windup-dev] New fernflower fork project

[Jess Sightler]

I have created a new project within Windup for maintaining a fork of 
Fernflower with Java 7 compatibility and a Maven pom. Maybe we can start 
releasing and keeping this up to date separately from windup core?

It is here:
https://github.com/windup/windup-fernflower

I think we can switch Windup to use this as part of 2.6.0, if noone 
objects to that.
