Adding some functionalities (basic filtering, timeline checkline, running tests optimization, global coverage calculation)

[ngreard]

• change the global coverage for chart : getting the value from estimated org coverage
• optimize running test call (since v37 can test all classes in my namespace or in all namespaces). Selection by radio button
• add top filter, included in the server query. For example : ApexClassOrTrigger.Name != 'MetadataService' and (NOT ApexClassOrTrigger.Name like 'fflib%'). The last filter is stored in the localStorage and reuse on refresh
• add number of classes displayed after filter applied
• add check mark on timeline item when completed
• add spinner (useful ?)

Great work ! Thanks for the contribution.
Could you please change the toogleLoading function name to toggleLoading ?
I think we should refactor the javascript and export the reset of the coverage in a proper module executable both in server and client side. Then we will be able to use it in this project.
Available to discuss about that and start a new project ?
