small resource fixes

fix: resource problem - horrible code that tries to produce different versions of the same resource - preevent file mixup in this case.

fix resource deps: generate more cleanly - no targets if there are no prereqs. no empty lines. fix resource copy performance: remove debug fix filters: behave if someone puts 2 identically named filters into the plugin dir by mistake.

fix performance: copy resources in the frontend. Helps cluster builds since remote copying is inefficient.
