Add the ability to live search through form field types

[DevinWalker]

Proposal: I think it would be a huge time saver to have a search feature in the field type selection modal:

Essentially, when a user clicks on the search and begins typing the fields filter based on the user's search request. Similar to Visual Composer's element search functionality if you've used that plugin before...
