Add ability to create fillable forms as in pdf

In many business applications, the user is given a fillable PDF form, in which some fields can be edited. Then the user can print the form, or upload the form. Without this capabiltiy the user must first print the form, and then fill it in by hand. The fillable form is much easier to read, and allows the application to upload it.

Javafx should have an option in FXML to create a fillable form. When the Javafx application opens this FXML file, only selected fields should be editable by the user. After editing, the user should be able to save the new FXML file or upload it.
