additional sidebar items

[leonieke]

Can a function be added that will add a .php page where people can add their own sidebar items?

The .php page can be an empty file (which won't give function-errors), but it can be edited (using a template we specify) by the users themselves.

For instance I would want to add my flickr.com link and also links to other pages (and of course money-making buttons!).

Idea as discussed on IRC:
Make a function for in the sidebar: blog_show_custom_items();
This function will fetch data from a table in the database:
id, url, text, image

If the image is set, it will show the image with a tags arount it and text as alt.
If the image is not set, the text will be shown with a tags around it

(In [30]) implemented user configurable links in main interface. Going to write admin stuff for it now.
