Enable HTMLReader as a Swift Package Manager dependency.

The only way to specify source files in SPM (as of Swift 3.0 preview 1) is by folder convention. This change should only affect those who manually copy or add the source files to their own Xcode project; hopefully that one-time inconvenience is worth enabling SPM.

 You have choices:
 
-* Copy the files in the [Code](Code) folder into your project.
+* Copy the files in the [Sources](Sources) folder into your project.
 * Add the following line to your [Cartfile][Carthage]:
   
   `github "nolanw/HTMLReader"`
 * Add the following line to your [Podfile][CocoaPods]:
    
    `pod "HTMLReader"`

 * Clone this repository (perhaps add it as a submodule) and add `HTMLReader.xcodeproj` to your project/workspace. Then add `HTMLReader.framework` to your app target. (Or, if you're targeting iOS earlier than 8.0: add `libHTMLReader.a` to your app target and `"$(SYMROOT)/include"` to your app target's Header Search Paths.)
 
 HTMLReader has no dependencies other than Foundation.
