Add Icon Selection Option on the Devtool's Model Creation Interface.

[zaghadon]

Normally when you create a Model, the Admin Sidebar is edited and updated with grammar guess of the Model StudlyCase name, and a general question (?) icon from the Backstrap Line Awesome Icons .

My idea is that two input fields should be added to the Model Creation Interface either on the far top right or the far bottom right where there are good empty spaces to accommodate them.

The inputs should be placed side by side with the following form components:

• A Checkbox (ticked by default) requesting whether or not to include the Model in the Sidebar.
• A Searchable Select (la la question by default) containing a grouped collection of all the Backstrap Supported Icons with the class name as value and the Icon and Class name as Display Text.

After a successful Model creation, this should then be used to automatically update the Sidebar view in the /views/vendor/backpack/sidebar_content.blade.php

This would save more time for the developer in having to scan through backstrap to find the desired Icon and Also going to edit the sidebar manually after spotting the desired icon.
