@description
This funtion prepares the Hyphenator-Object: If RemoteLoading is turned off, it assumes
that the patternfiles are loaded, all conversions are made and the callback is called.
If storage is active the object is retrieved there.
If RemoteLoading is on (default), it loads the pattern files and waits until they are loaded,
by repeatedly checking Hyphenator.languages. If a patterfile is loaded the patterns are
converted to their object style and the lang-object extended.
Finally the callback is called.
@param {function()} callback to call, when all patterns are loaded
