Hotpot (plugin)

Well done!
I see you manage to handle also the exception in JCloze, is a small inconsistence in the use of the xml tag. I'm not an expert but I see the module is an impressive work. Congrats!
I also modified the file:
\moodle\mod\hotpot\template\v6\jcross6.ht_
adding a buttton to allow the crossword to be restarted, something I couldn't figure out how to do in other way:

<button id="CheckButton3" class="FuncButton" Xonmouseover="FuncBtnOver(this)" Xonfocus="FuncBtnOver(this)" Xonmouseout="FuncBtnOut(this)" Xonblur="FuncBtnOut(this)" Xonmousedown="FuncBtnDown(this)" Xonmouseup="FuncBtnOut(this)" Xonclick="javascript:location.reload(true)"> Restart! </button>

But this is a "nice to have" for me.
I'm glad to contribute anyway!
Good job!
