Fixes #1596 by ensuring it only shows active members.

Currently removing a user from a group/org (marking membership as deleted)
then it still gets returned in dataset/new as a viable organisation/group to
choose when it isn't (as the user is not actually still a member).

Allows use of CKAN_INI env-var to locate config

Implements #1597

If you don't specify a config file using the -c option, CKAN defaults to
looking for development.ini in the current directory. This patch will
first check the -c parameter, and if it doesn't find it will use the
content of the CKAN_INI environment variable. If it cannot find that,
it will then default to development.ini in the current directory.
