A little something to help you find your nearest postbox

New features/improvements include:

• Registered users can now mark a postbox for deletion via the Edit page. Once marked the info window of the postbox will display a message showing that it has been marked for deletion. (marked postboxes will be deleted by myself at various times)
• The script that enabled images to display as an overlay has been changed (for those of you interested i'm now using Colorbox). This allows me to display dialog boxes and confirmation/error messages using the same UI as the images, giving the site a consistent appearance. (I am still working on an update for adding/editing feature confirmation and error messages)
• Graphical buttons added across the site instead of dull generic buttons

Thanks, any problems let me know in the comments.
