ansible.constants was calling expanduser (by way of shell_expand_path)
on the entire configured value for the library and *_plugins
configuration values, but these values have always been interpreted as
multiple directories separated by os.pathsep.  Thus, if you supplied
multiple directories for one of these values, typically only the first
(at least on *nix) would have e.g. "~" expanded to HOME.

Now PluginLoader does expansion on each individual path in each of
these variables.

Update ansible.cfg

Updated the example ansible.cfg to be more consistent in spacing/commented lines

remote_user should not be set in example config. This file is used in rpm .spec for /etc/ansible/ansible.cfg

Previous commit made config invalid.

Ensure an existing ssh-key returns useful information (id + name) instead of a string; this way it can be used to register a variable to use in a later task.

Generalise hacking dir path discovery

Merge branch 'generalise-hacking-dir-path-discovery' of git://github.com/madduck/ansible into envsetup2

enable use of multiple terms in first_found

A small error in the reuse of a variable caused packages to never get
purged. This commit fixes that.
