Issue #32: provide a client-side filtering system for search results of ...

...desktop strings

* refactor main view to be a bit more MVC
* Update Jquery reference to latest stable 1.x branch
* Show a row of button filters above the results
* Javascript to build the filters is created dynamically from the search results
This should work for the anchor part
```javascript
$(document).ready(function() {
    // We want URL anchors to also work as filters
    var anchor = location.hash.substring(1);
    if (anchor != '') {
        $('#' + anchor).click();
    } else {
        $('#filters a').removeClass('selected');
        $('#showall').addClass('selected');
    }
});
```
