* Change maiko downloads to account for draft releases #2

* Specify shell (powershell) for Download cygwin installler

* Few cleanup items on cygwin-install

* Update ShellWhich to use command -v instead of which because which returns to much crap on cygwin and command -v is more portable overall

* Switch from using medley-loadup & -runtime tars to medley-full-*.tgz so we get full release incl notecards; delete maiko on install and replace with cygwin maiko

* Add xdg-utils to cygwin install to support ShellBrowser

* Odds and ends on cygwin build

* Restore accidently deleted line to buildLoadup.yml

* Fix multiple issues with cygwin_installer filename; arrange to remove placeholder.txt from the release assets at the end of cygwin installer

* Fiddling with getting cygwin-installer name right

* Redoing merge of medley.sh/medley.command to handle the Darwin plus Cygwin cases; is medley.iss recreate symbolic links surrounding the medley.sh script

* Fix typos/syntrax errors in medley.sh/medley.command
