Adding AngularJS view templates

With this, the JavaScript code for our AngularJS app is in place, but we aren't done yet. We also need four HTML views for the app: The main view with the editor, plus three custom grid cell templates, one for the operations column that holds the Save and Delete controls, one for the Category column cells (because there we need to translate from category IDs to category names), and one for the Category cells in edit mode, because when we edit the category of a keyword, we don't want to edit its name as a string, but rather choose from a list of existing categories through a dropdown control.

We start with src/frontend/app/keywords/partials/editor.html:

< div class="span12" >
 <form>
    <input
      class="input-medium"
      ng-model="newKeyword.value"
      ng-init="newKeyword.value = ''"
      type="text"
      placeholder="Name of new keyword"
      >
    <select
      ng-model="newKeyword.categoryID"
      ng-init="newKeyword.categoryID...
