[ease-dev] Target platform change to Neon

[Christian Pontesegger <christian.pontesegger@xxxxxx>]

Hi,

in the last days I changed a lot of dependencies to move to a Neon-based 
target platform. The dependencies now require Luna as a minimum version 
for the core framework. Most of the modules also work under Luna. Only 
the modeling stuff has Neon as a requirement.

With this in place I moved the target platform forward to neon. So for 
all the developers out there please pull the changes and reload the 
developers target platform.

Finally if you are on neon and need the JSDT editor for javascript 
files, have a look at [1]. JSDT now depends on Nashorn/Java8 and needs 
some special run parameters to load all extensions correctly.

Thanks Jonah for starting all this work and investigating in JSDT.

cheers
Christian
