Updates to README

Of note, using latest XCode versions, this may save a lot of people some headaches.

6. In the ZXingObjC project, make the headers available for importing to your project.
   -- Select the ZXingObjC project, under "Build Settings" locate "Public Headers Folder Path"
   -- Enter "$(TARGET_NAME)" in the field.

If you are using ZXingObjC as a binary library, you may also want to set the directory where the library files are built.
-- Select the ZXingObjC project, under "Build Settings" locate "Installation Directory"
-- Enter "$(BUILT_PRODUCTS_DIR)" in the field.

1. In your project, make the headers of the library findable.
   -- Select the project, under "Build Settings" locate "User Header Search Paths"
   -- Enter "$(BUILT_PRODUCTS_DIR)" in the field.
2. Now, you can import the library headers, just like any other framework:

   import ... (can't put angle brackets in the text) ...

Thanks, I've decided to update the instructions to just describe adding the files directly to the project, with the note that CocoaPods can be used as well.
