Added distribution-picker to my_order page
Miscellaneous small presentation tidy-ups
Pass sub-paths to menu items, so can set contextual menu item from template path.
Redirect to index to home.php if logged in.
messages.done seemed to be lacking a default value for done, which is weird, because nothing sets it on insert... (and it was working)
Re-write of messages to remove XSS/code-injection potentials, and make the whole thing nicer.
