updated indentation and redundant comment.

bumping up min_count value.

I've uncommented and added a very little supporting stuff based on skvidal's work to allow us to launch more than one instance.

Fixed apt_key's add_key stalling indefinitely, and test code leaking into production

Add basic pkgin package management

ec2 facts module - registers to ansible_facts key

Git module: fix for relative paths

If a relative path is passed as an argument, this change first
converts it to an absolute path.

This fixes a bug where the git module would attempt to chdir into an
invalid directory because of multiple chdir calls against a relative
path.

This also fixes an issue where some console output for packages I was
installing was creating invalid JSON because it contained single-quotes.

Fixes #1918.

Inventory class - lambda fails on attribute access - g.name is a string not the group obje...

Adds user-selectable hash merging support in vars

Port ec2 module to Boto

Update docsite/rst/who_uses_ansible.rst

Added Eucalyptus.

Tests used heavily mocked version of the apt_key code, which meant that
it didn't properly test real life scenario.

Fixes #1902.

Fixes #1908.

pkgin always returns 0 so can't be used to tell if the install or remove
worked.  Instead this just queries the installed packages after
performing an operation.

Update apt_repository to query if repo is already configured

Update examples/playbooks/ansible_pull.yml

Typo

This adds two dependencies to the apt_repository module:  apt and
apt_pkg.  These come from the package python-apt.  This is used to parse
the host's sources.list and examine whether the repo is already
configured.  This then eliminates the unnecessary
'add-apt-repository --remove' from running.

No need for deep copy (vars are essentially immutable once loaded, there
should not be any modifications)

Minor doc fix: service module 'state' parameter comments should be processed by RST

Hash variables are currently overriden if they are redefined. This
doesn't let the user refine hash entries or overriding selected keys,
which can, for some, be a desirable feature.
This patch let the user force hash merging by setting the
hash_behaviour value to "merge" (without the quotes) in ansible.cfg

However, by default, ansible behaves like it always did and if any value
besides "merge" is used ("replace" is suggested in the example ansible.cfg
file), it will also behave as always.

protect PluginLoader._extra_dirs from appending None

PluginLoader.add_directory() can receive None from, for example, 
Inventory.add_directory(self.basedir()) if host_list is a custom list.
None has no reasonable interpretation other than ignore it.

Add pacman to list of package managers in setup module
