ShowItem 1.7.1.1 - Fix compatibility with old versions and special servers
Fixes some compatibility issues with very old server versions (namely 1.8.8)
Improves the detection for which version should be used for the internal adapter (1.7.1.1 fixes a bug in that)
Adds a new config option nms-adapter-version with which the internal version can be specified. (Defaults to "auto") This should never really be needed to get changed unless the plugin can't automatically detect it and prints an error on startup mentioning it.
