Title: Spouts and Bolts with whitespace in name can be viewed in ui

If you run a topology with a spout or bolt that contains a whitespace in the name (i.e. "Do some thing") then the URL towards the component page will look something like this:

/topology/TOPONAME-12-12345678/component/Do+some+thing

The page that is opened on that link will try to show a component called

Do+some+thing

which it doesn't have.
This fix is a simple URL decoding step for just the component field.
