Implement Quick Pins for Custom Forms for shortcuts to Layout Templates

[#1]

Custom Forms are an important use-case.

Many users have a need to see and/or input the Custom Form, but do NOT need to make four or more mouse clicks to get there.

The current Layout Template "Tabs" feature exists, but can only incorporate "Dashboards."

This proposal is to add a "Quick Pin" that allows System Admins to create/edit a Layout Template to attach a specific Custom Form.

This means that a specified user could have a default view that is directly and specifically to a Custom Form.

I like it! Even love the custom imagery you did :)
