postgresql_user module: Gracefully handle ALTER ROLE on read-only postgres servers.
Fix postgresql_user to understand PG namespaces

Previously postgresql_user quoted user supplied identifers to create
grant statements that look like this:

    GRANT SELECT on "tablename" to "user";

Which only works if the tablename is not in a namespace.  If you supply
a namespaced tabelname like "report.revenue" then it creates this
incorrect statement:

    GRANT SELECT on "report.revenue" to "user";

Which will not find the "revenue" table in the "report" namespace, but
will rather look for a table named "report.revenue" in the current
(default public) namespace.  The correct form is:

    GRANT SELECT on "report"."revenue" to "user";

This approach could have the unfortunate effect that code that
previously relied on the other behavior to grant privileges on tables
with periods in their names may now break.  PostgreSQL users
typically shouldn't name tables as such, and users can still access the
old behavior and use tablenames with periods in the if they must by
supplying their own quoting.
bugfix: support path separators in module path

As described by http://docs.ansible.com/intro_configuration.html#library the library supports multiple paths to load modules from. 

Currently `setup.py` treats something like `/usr/share/ansible:/my/custom/modules` as a single directory name and results in the installed modules not being on the module path. (instead they are in a directory named `/usr/share/ansible:/my/custom/modules`) 

This commit simply takes the first listed directory as the install directory for the core modules.
apt: fixed pkg=<name>=<version> fails if package is not yet installed.

Reported and patch provided by https://github.com/msolo. Closes GH-5625.
Fixes #5679: lineinfile ignores newline in line argument
Fix a bug in "hg" module so that `pull` is not set to a version.

There is a bug in the `hg` module where if a `tag` is used it won't
properly be able to update to it.

This problem is exhibited on repository where a tag is moved from an
older commit to a newer commit.
Make default ANSIBLE_REMOTE_PORT None

The ansible remote port should be None, not 22. Having a default value
of 22 means that '-o Port 22' will be appended to the ssh connection
all of the time. This is incorrect as when one would like to use
something like an ssh configuration file (-F) that sets the port to
something other than 22.

Part of this change requires that we check that, in get_config, the
value is not None before trying to cast it into an integer or float.
Fixes #5819: Added --executables to gem uninstall command.
Allow explict setting of vpc_security_groups to allow modification of security groups of RDS instances within a VPC
Fix broken behavior when removing all auxiliary groups from a user
(e.g. 'groups=' in the user module).
Adding 'validate_certs' option to EC2 modules

When disabled, the boto connection will be instantiated without validating
the SSL certificate from the target endpoint. This allows the modules to connect
to Eucalyptus instances running with self-signed certs without errors.

Fixes #3978
Merge pull request #5944 from sean-/devel

Fix broken behavior when removing all auxiliary groups from a user. See #5933 for more details.

Tests by hand correct and passes "make clean tests".
Filter out messages that match the pattern username:password@host

This filtering is done in both the module invocation logging and in
the regular verbose() logging output.

Fixes #4087
Updating CHANGELOG for the new validate_certs feature

Also removing validate_cert option from the cloudformation module docs,
as it does not use the standard ec2 connection.
Merge pull request #5998 from jimi-c/issue_3978_boto_ssl_cert_validation

Adding 'validate_certs' option to EC2 modules
Small fix for ec2 validate_certs option
Merge pull request #6002 from chrishoffman/ec2_validate

Small fix for ec2 validate_certs option
Add the start of an integration test structure using Ansible playbooks, also added an assert action plugin to make writing those easier.
Remove fixme and extraneous file.
