Ye Ol' π Shack

Dupe doc files that were removed:

  Bwbasic-3.2-options.txt -> ../DOCS/BYWATER.txt
  Bwbasic_3.20_manual.docx -> "docx" version of ../README
  Bwbasic-changelog.txt -> ../README
  Bwbasic-2.1-Manual.txt -> Bwbasic-2.1.doc
  Bwbasic-Doc-2.1.txt -> man-ified version of Bwbasic-2.1.doc

Since these are duplicate files their content has gotten / will get
out of date. Removing them prevents erronious information.

Document files renamed for consistency:

  Bwbasic.doc -> Bwbasic-3.20.txt
  Bwbasic-2.1.doc -> Bwbasic-2.1.txt
  Bwbasic-1.1-Manual.txt -> Bwbasic-1.1.txt
