JhlClientAdapter - modified to test that native library is 1.3.x and if it isn't, then treat it as if the library was not found.  We were already doing something like this for 1.2.x to make sure it didn't get a 1.1.x library.  By verifying that the library is not compatible, this allows Subclipse to automatically fall back to JavaSVN as the default.
