Make the version number a single number on native and java side.
Also, remove the hasValidContents method. It's useless since the
native code already checks this when creating the dictionary (I
wish I had known that when I added it).

This implements the skeleton implementation, and enables a
fallback implementation in the case the file is coming from the
dictionary provider.
- A better scheme should be used for provider-supplied dicts.
- This does not implement the solution for device-generated
    dicts yet. This will come in a future change.
- This does not implement the checking process on the native
    side yet. This will come in a future change.
