Improved exportMarkdown() & getName() to better preserve user input:

* Maintains proper carriage returns in markdown output
* Indented spaces / tabs are converted to   then run through ExportMD

Also added stub code to improve readability of exported filenames, but this will likely also require changes to some of the Rust code

scripts/export.js
