Empty or non-existent _posts folder results in "Unprocessable Entity"

[dstaley]

Steps to reproduce:

1. mkdir no-posts-folder && cd no-posts-folder && reptar init
2. rm -rf _posts
3. reptar watch

Expected result:

Reptar renders _templates/index.html with an empty loop.

Actual result:

{
  "statusCode":422,
  "error":"Unprocessable Entity",
  "message":"Cannot read property 'assetProcessor' of undefined"
}

Fix I went with was to show a prettier error message. The default scaffold site has the index.html file derived from all the files on your page, without any files then that file doesn't exist. So to have an empty loop is actually a lot harder than it might appear.
