include lib/* just after lib/app/*
refactor per-manifest replacement
whoops, prefixFirstLine shouldn't be tabbed
default grunt task includes rebuilding manifests
lib/**.* --> XPI/data/  not XPI/

is that right, @thybag?
refactor resourceFiles into incomprehensibility
manual manifest listings for lib/core/ js files
manifests w/ replaced values go in temp/manifests/Browser/
extension source built into temp/ext/Browser from Browser/, lib/, /temp/manifests/Browser
