Fix actions Permission for retire in roundup/actions.py was with 'Edit' permission, not 'Retire' permission. Add a 'restore' action to roundup/actions.py. Both are now correctly used in rest.py and xmlrpc.py (the latter had some errors when printint error messages). Also reworked the rest implementation: Despite the warnings in the roundup API in hyperdb.py the DELETE http method would *destroy* and not *retire* an item. This has been fixed. We also do not allow retire of a complete class (although this was implemented) because this seems to dangerous and we see no use-case.

# In Python 3 the "anydbm" module was renamed to be "dbm" which is now a
# package containing the various implementations. The "wichdb" module's
# whichdb() function was moved to the new "dbm" module.

try:
    # old school first because <3 had a "dbm" module too...
    import anydbm
    from whichdb import whichdb
except ImportError:
    # python 3+
    import dbm as anydbm
    whichdb = anydbm.whichdb
