homebrew issues

[blackketter]

The main README.md says to use "brew cask install vimmotion" which isn't correct. The command should be "brew install vimmotion"

Homebrew currently installs version 1.2, which isn't the latest. Upon running the app, an upgrade to 1.2.3 is offered and downloaded, but fails to install.

Downloading and installing the 1.2.3 .dmg file works fine.

I made a PR suggesting the README gets updated #27

Maybe the command should be brew install --cask vimmotion.
