Added LogEntries module
Fixed unfollow logic
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
Initial version of apt-rpm module
supervisorctl: add group support and refine documenation.
Expose the playbook to callback plugins
Introduce module layman
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
Add regex_replace jinja2 filter
Fix proper defaulting/required of 'state' for gem module

The docs for 'gem' say state is required, but the actual code says it's not required.

If it's not included (and there's no default) then the if block falls through with no changes and no errors (it neither adds nor removes the gem).

This change synchronizes the docs with the code.  It also adds the sane default of state=present, which is consistent with all other modules with the 'state' field.
Add 'vgoptions' parameter to lvg module.

Allows specifying extra flags to pass to `vgcreate`.
Added subnet tagging.
Added documentation for subnets: tags: option
Refactored subnet tagging to account for AWS delays; added 'tags' attribute to 'subnet' node in the returned json.
Renamed subnet's 'tags' attribute into 'instance_tags' to distinguish it from Ansible's own 'tags' and to conform to ec2 module naming for AWS tags.
