Update debuild to nw.js 0.15.4
Hi Jonathan, could you please merge this upstream? It updates the debuild stuff so that it is in sync with what I'm using again. Thanks.
The changes in debuild are:
debuild/Makefile, debuild/debian/rules: update nw.js to 0.15.4
add a command in the rules file to remove the dejavu font from the package (however, this is still commented out right now because it trips other rendering issues, as I already reported)
