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.

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.

Tell user to make inventory plugin executable

The current version mentions nothing about chmod +x'ing the rax.py file, which means you get a really weird error message when you try to follow it:

```
raise ValueError, "No closing quotation"
```

... from deep inside shlex.py. I'm sure that makes sense if you realized that meant that it was trying to parse `rax.py` as an ini file...
Revising method for parsing ranges from --limit subsets
