New cli supporting nearly all config options thanks to subarg

I think it makes sense to roll the CLI into atomify proper like this. This doesn't (yet?) support the atom generation or testing server found in `atomify-cli`, but it does provide much more robust support for bundling. All of the following commands are valid and supported. (Depends on the `atomify-js` PRs I submitted yesterday.)

```
atomify -j entry.js -c entry.css -o bundle
atomify -j [ main.js output.js ] -c [ index.css bundle.css ]
atomify -j [ entry.js -o out.js -d ] -c [ entry.css -o bundle.css -v [ --bgColor green ] ]
atomify -j [ entry.js -d -w -t deamdify -t debowerify ] -c [ entry.css -v [ --bgColor green ] ] -o bundle
```
