Replace "Cancel" buttons from the modals with "Cancel" link
In the current UI, the main action for a form is represented by a button element (eg: Create, Create and continue, Add, etc) and the "Cancel" action is represented by a link. This is a very useful because the main action should be more evident for an user.
In the modals (Export to CSV, Add watchers, Add members), both actions (main and cancel) are represented by a button and this is confusing. The attached patch replaces all the cancel buttons from the modals with the same "Cancel" link used in the rest of the app.
