Handbook PDF Generation wkhtmltopdf ProtocolUnknownError

[crumgary]

Describe the bug
When generating the PDF handbook wkhtmltopdf issues a ProtocolUnknownError message.

This seems to be a known issue. Under Linux the Handbook tool recommends using an obsolete version of wkhtmltopdf. Windows does not have that message (that I saw).

Environment (please complete the following information):

• OS: Windows 10
• COSMOS Version 4.4.2

Possible Solution

I found this issue on the wkhtmltopdf github site: wkhtmltopdf/wkhtmltopdf#2660

The solutions was to add the option --enable-local-file-access

Here is where it would go:

COSMOS/lib/cosmos/tools/handbook_creator/handbook_creator_config.rb

Line 118 in 5d2cdc5

system_call = "wkhtmltopdf -L #{@pdf_side_margin} -R #{@pdf_side_margin} -T #{@pdf_top_margin} -B #{@pdf_bottom_margin} -s Letter #{header} #{footer} #{cover} #{@pdf_toc} \"#{tmp_html_file.path}\" \"#{File.dirname(filename)}/#{File.basename(filename, '.*')}.pdf\""

I tested this in a Windows 10 environment and it seems to work. I can create a pull request.
