TODO:

- change the behaviour of the filters menus: they should not close on select (they should stay open so that you can check / uncheck multiple checkboxes)

- display a no-results found message when a search does not return any results (all tables)

- we might consider adding a link to the all layers and all recipes tables from the layer details page

* Need an "About" section descriptibing what the site is for
* Need an admin contact in footer
* Some columns are a bit crushed
* Description is not formatted nicely on detail page
* Need to show on detail:
 * Last commit date
 * Last update date
* Usage links in list page?
* Layer submission interface design
* Recipe info page
* Captcha for layer submission interface?
* Touch up publishing interface
* Show layer notes records

Later:
* Ability for users to edit existing layers
* Something to help with compatibility (although maybe this should just be handled using the existing versioned layer dependencies in layer.conf)
* Query backend service? i.e. special URL to query information
* Tool for finding/comparing duplicate recipes?
* Tool for editing SUMMARY/DESCRIPTION?
* Dynamic loading/filtering for recipes list
* Collect information on machines added by BSP layers?
