Title & Meta date variables localization

I noticed when using %%currentmonth%% in our meta description that even though our site is in Danish, the output was in English. I searched the source code and the web and discovered that you use the date() function. Changing the function call to date_i18n() seems to do the trick, but I don't know the code very well and cannot really tell if this is the correct solution to the problem.

However, this error is somewhat critical because it can do more harm than good if users assume that the plugin uses the wordpress date formatting.

cheers!
