Add template for sample .info applications

[tejaede]

The goal of this template is to quickly stub a prototype application for a single component. This template adheres to the standard montage pattern of creating a .info directory as a direct sibling of its associated component.

Example	Component	Command	Output
ui/list-item.reel	minit create:sample -n list-item	ui/list-item.info
ui/button/custom-button.reel	minit create:sample -n custom-button -d ui/button	ui/button/custom-button.info

Structure The output is based on the app.js template with a few key differences:

1. test and run-tests.html are removed

2. The package dependencies are replaced with mappings back to montage and the main package.

   {
   "name": "list-item-sample",
   "version": "0.1.0",
   "description": "sample",
   "mappings": {
       "montage": "../../../node_modules/montage",
       "acme-framework": "../../../"
   }
   }

3. The montageVersion component serialized in ui/main.reel is replaced with an instance of the component being prototyped.

       {
           "owner": {
               "values": {
                   "element": {"#": "main"}
               }
           },
   
           "listItem": {
               "prototype": "acme-framework/ui/list-item.reel",
               "values": {
                   "element": {"#": "listItem"}
               }
           }
       }
