Added LogEntries module
Fixed unfollow logic
Added replace module

Heavily based on existing lineinfile module, but where it literally tests a regexp against
*each individual line* of a file, this replace module is more analogous to common uses of
a `sed` or `perl` match + replacement of all instances of a pattern anywhere in the file.

Was debating adding `all` boolean or `count` numeric options to control how many
replacements to make in the destfile (vs currently replacing all instances)

Noted use of MULTILINE mode in docs, per suggestion from @jarv
Add a `recursive` option to the git command.

Make it possible to clone without submodules by setting
recursive to no. Default is yes, so no change is needed
in existing plays.
support for apt-key keyserver parameter
Adding 'export' option to subversion module (to export instead of checkout)
Make default irc color none; add color none
Initial version of apt-rpm module
supervisorctl: add group support and refine documenation.
Expose the playbook to callback plugins
Make vars plugins honor `hash_behaviour` setting.

When applying precedence ordering of different classes of vars
(hostvars, groupvars, role-defaults, etc.), the hash_behaviour
setting controls whether duplicate hash keys are replaced in
entirety, or merged together.

The wording of the documentation suggests that this setting applies
to all levels of the precedence ordering, when it currently does not:

> Ansible by default will override variables in specific precedence orders,
> as described in Variables. When a variable of higher precedence wins,
> it will replace the other value. ... Some users prefer that variables that
> are hashes (aka ‘dictionaries’ in Python terms) are merged together. This
> setting is called ‘merge’.

This change causes the hash_behavior setting to extend to vars plugins.
Introduce module layman
Add typetalk notification module
adding the ability to change redis configuration
add registry option to npm module
Started the development of the 'chdir' functionality for file module - creation symlinks without the base directory prefix
Found a way how to have symlinks towards files without absolute paths in prefixes; fixed incorrect force setting on the hard links, which can not point to non-existing files
Updated the force parameter description; added one example how to create the symlinks pointing to non-absolute paths
apt module: Add support for installing .deb packages

Support installing .deb packages from the local filesystem.

    apt: deb=/tmp/mypackage.deb
Adding example for svn export
