TextClassification plugin for GATE

Just to let you know that I've made public our TextClassification plugin for GATE. As its name indicates, it is a GATE plugin which uses
our TextClassification API for building a training corpus from
GATE documents or classify GATE docs with an existing model.

This code
has been around for some time but I did not find the time to make it
public until now. Since I regularly get emails asking me about it, I
thought it would be simpler to release it.

As usual, it is under the Apache Software License and will (maybe) get
a better documentation soon. For those of you familiar with the TC
API, this should be quite straightforward.
