Add get_meta in LDAP::Simple
Allow dash in filename for Connector::Builtin::File::Path
Add support for connector leaves in get_hash
Enable die_on_undef in Proxy::Config::Versioned->get
Fix spacing and indent, no code changes
Improve handling of undef/non exisiting file in File Connectors
Allow recursive connector/reference use, change get_meta stub

Connector::Multi now uses itself (not baseconnector) to resolv
links to connectors, which allows references inside connector
definitions (e.g. LDAP Password via KeyNanny)

The definition of get_meta method no longer includes optional return of
the value and does NOT NECESSARYLY test for exisitence of a node any longer.
If you used get_meta to test for existance, please check if the used
connectors support it.
Add generic get_size / get_keys
Add/Change get_meta methods in all connectors to match new requirements
Add get_reference call in C:P:Config::Versioned
Fix spacing in Proxy::DBI
Allow retrieval of top node in Proxy::YAML
Add tests for cascaded references / connectors
New connector Authentication::PasswordScheme

Check passwords from a file with {scheme}hash notation
Introduce new method exists as replace for old get_meta functionality

As get_meta no longer checks if the node exists, this is a new method
to check safely if a node exists.
Implement exists in all connectors (except SOAP::Lite) and add tests
Add stubs for get_meta and exists in SOAP::Lite - not working

Class implements hash and list and does not have any confg to determine
the type - need to be split into two classes or invent config value.
Minor fixes and improvements
Change "return undef" to "return"
Fix bug with exists and array notation, add tests for this
