Support slot and replace-part template replacement.

@ppn2 commented on Tue Aug 09 2016

Many times while using slot and replaceable template, the target element might introduce overriding context. At this moment the linter does not recognize that.

Example (I have omitted the view models for bravity)

--some-element.html
<template>
  <div repeat.for="item of items">
     <template replaceable part="item-template">
         ${item.itemName}
      </template>
  </div>
</template>

Usage:

--main.html
<template>
  <some-element>
    <template replace-part="item-template">
      <div style="color:blue">${item.itemName}</div>
    </template> 
  </some-element>
</template>

In this case linter will look for the item property in the main.ts and raise it as error. Similar behavior can be seen with the slots.
