more cache updates
set default cache timeout at end of Options init, to ensure the correct cache is checked
auto-generated modelform fields will now properly handle length restrictions
debug lines removed
killcache management command can now take positional arguments: manage.py killcache <model_name> [<id> <id> ...]
include namespaces during cache list key generation
Init version keys to timestamp, to prevent expired version keys from referring to stale caches
Set options.base_model_name during Options setup, rather than checking the mapper in a property.
