Add support for glob patterns in single quotes for files and exclude arguments

PR checklist

• Addresses an existing issue: using tslint cli as npm script has inconsistent path behavior for windows and linux #1639 (related)
• New feature, bugfix, or enhancement
  • Includes tests
• Documentation update

What changes did you make?

There were three ways to pass globs in npm scripts were mentioned in #1639:

1. Without quotes src/**/*.ts
     - works on Windows (src/**/*.ts is passed to process and matching is done with glob module)
     - doesn't match all files on Linux (see Normalize glob matching between Linux and Windows during TSLint build. Fix lint error. #1678)

2. With single quotes 'src/**/*.ts'

• works on Linux (src/**/*.ts is passed to process and matched with glob module)
• doesn't match anything on Windows since process receives quotes string as argument 'src/**/*.ts' and glob returns no matches with quotes

3. With double quotes "src/**/*.ts"

• works both on Windows and Linux (src/**/*.ts is passed to process and matching is done with glob module)
    - requires escaping in package.json file (e.g. "lint": "tslint \"src/**/*.ts\"") which hurts readability and might lead to errors if code editor doesn't notify about errors immediately

First case is OS specific and can't be addressed in TSLint package, but second might be properly handled.

This PR simply clears single quotes that may appear on Windows platform if glob is wrapped in single quotes in npm script.
Main intent is to increase interoperability between platforms and make npm scripts easy to write/read.
