Based on @omz script Add to Home Screen,
this script allows the creation of an home screen shortcut to run a script
- to be selected in Pythonista local or iCloud files
- to define any icon web file, not only builtin icons
- to add eventual arguments to the url scheme
The safari page to share to an home screen shortcut shows the icon, its url, its title and the url scheme.
These informations need to be entered in a form_dialog:
- when you put the cursor on the script field, you get a file picker
- when you modify the icon url, the image is directly showed

As it is called by a form dialog, I've had to modify it because the scrolling did not work, perhaps due to two successive wait_modal.
