Set source compatibility to Java 1.7
Get version name constant from BuildConfig
Extract Cloudinary.Configuration to its own class
Make Configuration object immutable.

Don't want to get bitten by surprise changes to the configuration object.
Die with an IllegalArgumentException if we try to build a CloudinaryObject from a context that doesn't have a CLOUDINARY_URL

More useful to get an exception here than to continue with a broken configuration.
Replace custom and unchecked emptyMap with Collections.emptyMap
Change identifierPattern to static final Pattern IDENTIFIER_PATTERN for readability
Rewrite Cloudinary config url parser to use Builder
Rewrite CloudinaryTests for the new immutable Configuration class
Suppress the UploaderTest by default since it requires you to have a cloudinary
account set up correctly to run and will upload images to the cloud

If you want to run the tests make sure you've got the correct settings in
androidTest/AndroidManifest.xml and then uncomment the @Suppress line
Update README.md
