Remove unneeded type field from anchor tags in teams markup
Adding delete modal to volunteer account page

**Changelog:**

 - Added modal for deleting the volunteer account to the volunteer account view at `server/views/volunteer-account.html`. This modal does not require any JavaScript to function at all. It is activated by any link that has a `href` attribute consisting of a hash-tag and the modal element's `id`. The confirm delete link within the modal sends a GET request to either `/volunteer/account/delete` or `staff/volunteer/account/delete/:id` depending on whether the user is a staff member.

 - Changed the HTTP request type for `/staff/volunteer/account/delete/:id` from `POST` to `GET` in the router at `server/router/index.js`.

 - Made the jQuery calls more efficient by, after getting the form element, only only searching the `form` elements descendents for the remaining DOM queries.
