Nessus Improvements Extension

Currently, this changes the following:
\t• Fixes clickable height of \"Back to\" link.
\t• Adds links to table name cells so that they can be middle- and right-clicked to open in new tabs.
\t• Adds button to scans to copy a file name. This also automatically replaces Windows invalid characters (refer to https://mythofechelon.co.uk/blog/2020/3/6/how-to-work-around-windows-restricted-characters).
\t• Makes scan and vulnerability table columns more space efficient by decreasing the width of some and removing redundant ones.
\t• Moves notifications so that individual or multiple notifications don't block the buttons or sub-buttons.
\t• Removes maximum width limitation on scan title headings.
\t• Increases width of scan configuration input fields.
\t• Enables resizing of textareas.

By default, only works with the URL https://localhost:8834/ because using broader permissions requires manual reviewing which increases the publishing time enormously (from minutes to days or even weeks). If you use a custom URL (DNS name and/or port), do the following:
\t1. Close all instances of Google Chrome. This writes the latest configurations.
\t2. Edit the file \"%localAppData%\\Google\\Chrome\\User Data\\Default\\Preferences\"*.
\t3. Do a find-and-replace-all using the following parameters (including the quotation marks):
\t\t• Find: \"https://localhost:8834/*\"
\t\t• Replace with (option #1): \"https://localhost:8834/*\",\"https://YOUR_URL/*\"
\t\t• Replace with (option #2): \"https://*:8834/*\"

Last tested on Nessus Professional version 8.10.1 (latest as of 2020/06/25).

Changelog / version history is available at \"%localAppData%\\Google\\Chrome\\User Data\\Default\\Extensions\\dbnnngkmpjaigkjjikdmihpocggbglgg\\\
otes\\Version History.txt\"*.

* The folder \"Default\" may be named something like \"Profile 1\" if you have multiple profiles.
