mktemp creates the temp directory 700 only.  If the sudo-user is not
root, the other user will not be able to run the command (Permission
denied error).  This adds the executable bit for all on the temp
directory.

Allow camelCase variables in varReplace.

Added parameter to the apt-get install command to prevent interactive conflict resolution

Fix hang on large command output.

Support single handlers for notify.

Fix YAML hosts list.

Support list indexing in varReplace.

Fixup unicode varReplace templating.

Fix for bug #264

The original patches should have conflicted?

override-hosts is gone since we can't load inventory for hosts (so it's not an whitelist), but we can
still support hosts outside of inventory if you pass in an array of hosts.  Ports are supported,
but not much other info.

Support nested variables in varReplace

Preserve trailing newline after templating.

Jinja seems to eat trailing whitespace. A lot of tools complain about this: iptables-restore, iscsid...

Template dest and src parameters

User module fix

Resolves issue #333.  If spwd is not available, the password will
be set regardless.

Issue122 - have all modules log to syslog

Support for branches in git module

Allow unicode (utf8) in templates

The ohai and facter modules use /usr/bin/logger to log the fact that
they have been invoked.  I added 'import os' to the ping module
so that it could have the same syslog statements as the other modules.
I separated the condensed:
    shlex.split(open(argfile, 'r').read())
into two separate statements similar to the other modules.
