release jquery-bbq-v1.3

[binki]

The jQuery.fn.hashchange() in jquery-hashchange-v.1.3 is not included in the relatively standard jquery-ba-bbq-1.2.1 minified version. I’m not sure what else has changed in jquery-bbq itself, but to get the new hashchange code, it would be nice to have the user get the hashchange minified version separately from jquery-bbq or for the combined minification to at least have the best version of each plugin.
