Use unminified file in "main" in bower.json

[As per Bower's commands](https://github.com/bower/bower.json-spec#main).

Side note: I've been thinking of including `textAngular-sanitize.js` but it's not really mandatory. Is there any way to actually use `angular-sanitize.js` and override the usage of it? That way we can include `angular-sanitize.js` to the dependency and add the overrides to the main (or add them to `textAngular.js`).
Added textAngularSetup.js to 'main'

Didn't notice textAngular.min.js was a minified version of the combined two.
