improve error trapping for md5

Allow variables in variables in templates

Fixed: executing templates outside playbooks

Authorized key fixes

Fixes ansible/ansible#522, no longer creates comment in ~/.ssh/authorized_keys, does not create directory or file if state==absent.

Fixes ansible/ansible#523. Removed 'with:' blocks so module works with Python 2.4 for CentOS 5 support, courtesy of mcodd/ansible@29af24b73222c97e30f5843b67e321b95fb6c979.

Updated the file module to handle the case where the UID for the file doesn't exist on the system.

Remove the -D module debug flag, which no longer is functional due to sudo pty requirements, and replace with -v/--verbose.

This flag will show playbook output from non-failing commands.  -v is also added to /usr/bin/ansible, but not  yet used.

I also gutted some internals code dealing with 'invocations' which allowed the callback to know what module invoked
it.  This is not something 0.5 does or needed, so callbacks have been simplified.

Correctly add ungrouped hosts to 'ungrouped' in YAML inventory.

added ability to ovverride all ssh settings via ANSIBLE_SSH_ARGS

Add basic support for Solaris

Add ./library to module search path.

It allows for custom modules in the best practices directory structure.
Bundling custom modules along with playbooks in packages is useful.

Import ansible errors in Poller.

Copy module: Error handling for missing permissions on the copy destination.
