Draft: parameters to control array options in the task panel

Use the value of the parameters `Draft_array_fuse`
and `Draft_array_Link` to set the default value
of the `Fuse` and `Link array` checkboxes in the task panels.
These default to `False` and `True`, respectively.

Whenever the user toggles a checkbox
the new value of the parameter is stored so that when
the command is used again the last state of the checkbox
is remembered.
