Remove package-lock.json and add stars (*) to devDependencies in package.json

[adamjohnson]

Steps to reproduce the issue

View package-lock.json and package.json at the root of the project.

Results

Both of these files are locking the major version numbers of the packages they use.

Expected results

With the exception of Gulp (?), other devDependencies should not list a version number in package.json. It should list a star (*), like so:

{
  "devDependencies": {
    "gulp": "^3.9.1",
    "gulp-sass": "*"
  }
}

package-lock.json should be deleted from this repo. It will be created per-project upon npm install.

By following these guidelines, it will:

• Ensure we're using the latest versions of the requisite packages
• Help with compatability (using old tech > stuff doesn't work > solution = update to latest version)
