NIHVIVO-2280: Created js file to handle: filtering in ascendant and descendant order for email, first name, last name, status, and count columns on main account page.

Also created js alert for deletion of accounts, and created custom message depending on how many account user deletes.
1 account message: Are you sure you want to delete this account?
More than 1 account message: Are you sure you want to delete these accounts?
