Change schema querying to allow recursion for inherited attributes.
Fix do_show scope handling to match do_search (as per df67f598821c7cdaa089ce0b62385de1c3eb7355)
Make do_show() output ldif instead of a pretty-printed object.
Move ldap-ldif conversion into LDAPSession methods.
- Use these in do_editor() and do_show()
- Import StringIO to work around ldif module's reliance on file-handles
Remove pprint import as ldif can be 'plain' printed
