moved dashboard stuff into a feature folder, not sure about this, but need better structure and better way to organize dependencies

Allow for plugin testing.

Bring panel alert to front and move tooltip to top.

This makes the panel a lot easier to mouse over without odd visual effects.

With this change in place you can include plugin specs in `grunt test` by creating a `src/config.js` like that includes something like this:

```js
      plugins: {
        // list of plugin panels
        panels: [],
        // requirejs modules in plugins folder that should be loaded
        // for example custom datasources
        dependencies: ['grafana-plugins/atlasDatasource'],
        specs: ['grafana-plugins/specs/atlasDatasource-specs']
      }
```
