    cooker.py: add LAYERRECOMMENDS processing
    
    Add recommended layers to collection_depends[] so that dynamic
    priority assignment will work for both depends and recommends.
    
    Recommended layers do not cause an error or warning
    if they are not in the collection list, but debug messages
    are output for level 3 and above.
    
    explode_dep_versions2 returns a dictionary, so we
    change the variable deplist to depDict.  The dictionary
    values are lists which are either empty or contain only one
    version specification.
