Based on mailmate/macvim.mmbundle by O'Shaughnessy Evans, see https://github.com/mailmate/macvim.mmbundle
Modified for VimR as described by Giovanni Lanzani, see https://lists.freron.com/mailmate/2017-October/008787.html
Edit file "Support/bin/edit" to add the directory, where VimR's vimr CLI tool has been installed, to PATH.
Edit file "Commands/Edit.mmCommand" to change 'keyEquivalent' to the desired hotkey (default is Ctrl-1, opposed to Mailmate's default of Ctrl-Shift-O for external editors).
