Dashboard config

Good evening,

Some small changes to the code i previously commited.

- As requested, changed the name of the method (getParameterValue => resolveParameters). Fair point.
- Also solved two small bugs that sneaked (snuck?) in somehow. 
- Added alpha-numerical sorting on the dashboard keys among the custom parameters. 
- Finally added some style formatting to the dashboard page (and refactoring some of the old css mixins in the html)
LinkedHashMap retains the insertion order, but doesn't do any sorting. I think you should use TreeMap.
