Install osascript instructions not clear enough

[waqasrana]

running thyme dep on osx gives instruction
npm install --save osascript'

running which prints error
npm WARN saveError ENOENT: no such file or directory, open '/Users/<username>/Project/thyme/bin/package.json' npm WARN enoent ENOENT: no such file or directory, open '/Users/<username>/Project/thyme/bin/package.json' npm WARN bin No description npm WARN bin No repository field. npm WARN bin No README data npm WARN bin No license field.

maybe tell user (like me) who doesn't knows much about npm much to run npm init first and fill with this repo's data.

npm install --global osascript

Should be in the docs, rather than --save

Actually.. this is wrong, too.

You shouldn't have to install osascript on a mac at all..

I mistakenly thought some people might due to #11. Thanks for the revert!
