Add MacVim test scripts for basic testing

Just initial commit to do very basic regression testing including
checking options/commands exists and that we can map keys. May add more
later. Some more complicated tests probably need Objective-C tests but
for simple things we should be able to rely on VimScript tests to be
consistent with how Vim does things.
