Add ability for some manifest attributes to reference resources.

This loosens our restriction on many manifest attributes requiring
literal string values, to allow various ones to use values from
resources.  This is only allowed if the resource value does not change
from configuration changes, and the restriction is still in place
for attributes that are core to security (requesting permissions) or
market operation (used libraries and features etc).
