[Feature Request] Use date format set by dformat

[SFITCS]

Priority low. I'm happy to keep hacking this feature into releases.
By default the plugin uses yy-mm-dd date format, regardless of what format is set in $conf['dformat'].
Unfortunately this does not suit Australia as we use the dd-mm-yy format.
I don't know how to automate the process of supporting the format set by $conf['dformat'], but it's currently a simple hack to force dd-mm-yy.
