Convert to and enable staticfiles contrib application

This moves our site static files into the sitestatic directory if they
are shared resources, and also moves a handful of things (such as the
artwork logos) into application-specific static/ directories. This
allows the staticfiles contrib app to work after a few settings tweaks,
a run of collectstatic, and massaging the hardcoded '/media/' prefix out
of our templates.

Django 1.4 is going to make this a lot easier to move things to a CDN
and provides better template tags; for now this is setting the stage
before we can move to that.

- * 

- * @description Create a sortable table with multi-column sorting capabilitys

- * 

- * @example $('table').tablesorter();

- * @desc Create a simple tablesorter interface.

- * 

- * @example $('table').tablesorter({ sortList:[[0,0],[1,0]] });

- * @desc Create a tablesorter interface and sort on the first and secound column column headers.

- * 

- * @example $('table').tablesorter({ headers: { 0: { sorter: false}, 1: {sorter: false} } });

- *          

- * @desc Create a tablesorter interface and disableing the first and second  column headers.

- *      

- * 

- * @example $('table').tablesorter({ headers: { 0: {sorter:"integer"}, 1: {sorter:"currency"} } });

- * 

- * @desc Create a tablesorter interface and set a column parser for the first

- *       and second column.

- * 

- * 

- * @param Object

- *            settings An object literal containing key/value pairs to provide

- *            optional settings.

- * 

- * 

- * @option String cssHeader (optional) A string of the class name to be appended

- *         to sortable tr elements in the thead of the table. Default value:

- *         "header"

- * 

- * @option String cssAsc (optional) A string of the class name to be appended to

- *         sortable tr elements in the thead on a ascending sort. Default value:

- *         "headerSortUp"

- * 

- * @option String cssDesc (optional) A string of the class name to be appended

- *         to sortable tr elements in the thead on a descending sort. Default

- *         value: "headerSortDown"

- * 

- * @option String sortInitialOrder (optional) A string of the inital sorting

- *         order can be asc or desc. Default value: "asc"

- * 

- * @option String sortMultisortKey (optional) A string of the multi-column sort

- *         key. Default value: "shiftKey"

- * 

- * @option String textExtraction (optional) A string of the text-extraction

- *         method to use. For complex html structures inside td cell set this

- *         option to "complex", on large tables the complex option can be slow.

- *         Default value: "simple"

- * 

- * @option Object headers (optional) An array containing the forces sorting

- *         rules. This option let's you specify a default sorting rule. Default

- *         value: null

- * 

- * @option Array sortList (optional) An array containing the forces sorting

- *         rules. This option let's you specify a default sorting rule. Default

- *         value: null

- * 

- * @option Array sortForce (optional) An array containing forced sorting rules.

- *         This option let's you specify a default sorting rule, which is

- *         prepended to user-selected rules. Default value: null

- * 

- * @option Boolean sortLocaleCompare (optional) Boolean flag indicating whatever

- *         to use String.localeCampare method or not. Default set to true.

- * 

- * 

- * @option Array sortAppend (optional) An array containing forced sorting rules.

- *         This option let's you specify a default sorting rule, which is

- *         appended to user-selected rules. Default value: null

- * 

- * @option Boolean widthFixed (optional) Boolean flag indicating if tablesorter

- *         should apply fixed widths to the table columns. This is usefull when

- *         using the pager companion plugin. This options requires the dimension

- *         jquery plugin. Default value: false

- * 

- * @option Boolean cancelSelection (optional) Boolean flag indicating if

- *         tablesorter should cancel selection of the table headers text.

- *         Default value: true

- * 

- * @option Boolean debug (optional) Boolean flag indicating if tablesorter

- *         should display debuging information usefull for development.
