Add gnus, CMake, Java and Emacs daemon

Hello,
I have been using your configuration for about half a year now and I really love it. Therefore I added some cool things you might consider as useful:
+ A full gnus setup
+ CMake support (because I am more on the C level then in the web)
+ Java support through either native Emacs or Eclipse
+ A handy Makefile for "installing" Emacs as a daemon (currently only for systemd)
+ A very very simple erc config
