Minor polishing

* Updated application categories for pie charts to those agreed with Uppsala
* Removed lane load stacked bars for lib prep projects
* A few visual tweaks
Having seen @pekrau's Javascript book examples, I am convinced. I will change my ways.. (probably). For everyone else's benefit, here are a few of my favourites:

```javascript
'' == '0'          // false
0 == ''            // true
false == 'false'   // false
false == '0'       // true
false == null      // false
null == undefined  // true
' \t\r\n ' == 0    // true
```
