637. ECCE on Ubuntu 16.04.2

I just tried to build ECCE on Ubuntu LTS 16.04.2 according to http://verahill.blogspot.com/2015/06/611-building-ecce-on-debian-jessie.html and it worked without a hitch. The only things that needed changing were

* from openjdk-7-jdk in debian to openjdk-8-jdk in ubuntu
* src/inv/flclient/flfreetype.c: <ftoutln.h> needed changing to <freetype/ftoutln.h>

find *.mp4 -print0|sed 's/mp4//g'|xargs -0 -I {} avconv -i {}mp4 {}mp3
