fix reference errors for JS, CSS editors #3525
use 'lite' query engine in the build instead of 'acme'
Proper handling of root files.

Since this build.properties isn't part of a feature,
the root files props will only get run if they are set
as `generatedBuildProperties`.
root.permissions.* must be declared as a single line.
Can get rid of customAssembly.xml, since that's all
handled by the root.* props.
Fixes #3799
Merge branch 'master' into orion_1_0_3481
