#2375 "add to tools" checkbox should be on both code and UI screens

[Jeremy Faden]

The "add to tools" checkbox which adds a tool to the scientists Tools menu only shows on the script tab when a script is run, not on the "params" tab. It should appear regardless of which tab is showing.

I made the change for this a couple of weeks ago (2021 July 13 to JythonUtil.java, r23869) and I didn't notice this breaks one of the paths where this GUI is used:

1. in the address bar, https://github.com/autoplot/dev/blob/master/demos/tools/updateAutoplot.jy
2. the "Run Script" dialog pops up, only shows the message "Make sure this script does not contain malicious code."

This is fixed. Also I'd like to add the following tool tip to explain the script security:
"""Autoplot keeps track of what scripts you have run, and when
things change with a script you will be asked to verify
the script. Scripts can be made which delete files, so be
sure to only run scripts from people you trust."""

Also, there's a differences engine within Autoplot's source now, and it should be used to annotate parts of the script which change.
