Allow RESOURCES to contain standalone files and collections of files

Standalone files are added by using RESOURCES += file.txt, while
collections of files are defined as collection.files = f1.txt f2.txt
and then added using RESOURCES += collection. For collections a prefix
can also be set using collection.prefix = /foo. The standalone files
are not prefixed.
