* Main change: a distinct document is generated for the skippables, mirroring the original document's structure, in order to apply the CSS on the skippable as if they were never separated from the rest ;
* The Java CSS inliner is robust to misformed list of CSS sheets URIs;
* ATT: the voices returned by the ATT's TTS Service are only those which match the sample rate of the TTS Service (i.e. no resampling);
* Allow two different processors to output data in the same buffer if they share the same AudioFormat;
* New methods for the LoadBalancer interface to remove servers, list them and use one of them as a reference for querying general information;
* Added references to some of the Acapela's voices in the TTS registry;
* Fixed a bug in the dictionaries of skippable elements that stopped them from being fully pronounced (name + content).
