cleanup description escaping code

[oxinabox]

This cleans of a lot of the code that generates the text for the code for the descriptions.

• Discard all whitespace at beginning and ends of lines
  • this does change the descriptions that have full license text a lot but by #37 they shouldn't be there anyway.
  • but it fixes ones that have problems in their original description formatting (e.g. as was used to create test/references/DataCite Fire Patch.txt)
  • If a description needs indenting it is probably overly long anyway
• Use our own escaping code
  • before we were extending the base escaping code. But actually looking at it none of the base escaping rules were useful to us, so I tossed them and just used out extensions. All we actually need to escape is \ and $, escaping other things was actually creating worse code, wth \r and \" all through it.
    • delete and the vscode directory, that shouldn't have been version controlled in the first place (Something I missed during code review)
• We were escaping the descriptions twice, so this stops that.

I am using https://github.com/Evizero/ReferenceTests.jl/pull/6 because regenerating the this many reference tests with the release version of ReferenceTests.jl is utter pain
