Compatibility changes for Ruby 1.9

Some of the syntax I was using was not Ruby 1.9 compatible.  This commit
corrects that oversight.
Added support for keys without leading slashes

This commit removes the requirement that a key be prefixed with a
leading slash.  Both a leading slash and no leading slash are now
acceptable for remote_path.
Not tracking autogenerated metadata.json

This file is autogenerated and does not need to be in version control.
Incrementing version number

Accidentally uploaded a debug log to Chef community site. Have to
increment version number to get latest version not to have that debug
log.
