MacVim Snapshot 154

Vim patch 8.1.873

Targets macOS 10.8+

General:

- MacVim binary is now signed by a Developer ID (#517). This makes it
  easier to download and run the app without security warnings.
    - This also fixes an issue where invoking external programs via
      `:!open` was slow in Mojave. #763
- Ruby version has been updated from 2.5 to 2.6.

Fixes:

- Scrollbars are no longer misplaced when resizing window #827
- Fix rendering performance issues for commands (e.g. `:version`,
  `:echo`, or `:!`) that echo text in Mojave #840
- MacVim now properly asks for permission to use AppleEvent (ODB Editor
  Suite requires that to work) #822
- Fix borderless window mode in pre-Mojave versions #828

Script interfaces have compatibility with these versions:

- Lua 5.3
- Perl 5.18
- Python2 2.7
- Python3 3.7
- Ruby 2.6
