Topics and Tags Should Toggle

[lindsaycaron]

Because alliteration is good.

Currently, to undo a selected topic, user must hit 'clear'. This is not an intuitive user scenario. They should click on the highlighted topic to deselect.

Hey,

So I took a look at this along with #82 and the only solution that came to mind was changing the tags to form checkboxes that the user can submit once they select multiple Types/Topics. The POST request gets fired with only one Type/Topic after any one tag is selected to the controllers, so there needs to be a submit button or something to allow multi params. Anyway, I'll make a pull request if you want me to implement that approach.

Cheers!
