Text input directive applied to inappropriate input elements

For example, an gets the textInput directive applied. It's not very useful. Directive stacking means it's not a huge deal, since you can apply your own directive on top. But I like the cleanest possible approach. My change uses the "type" property, which allows the browser to decide what type an input is going to be (defaulting to "text" if need be) and then only applies the directives for matching types.

You've already got a PR open for this, you don't need to open a separate issue :) Closing this and directing people to the PR at #6243
