Fix to relevant and fieldlist groups

[jluis859]

This code in data.js:
if (relevance.length > 0 )
binding.attrs.relevant = '(' + relevance.join(') and (') + ')';

Should be:
if (relevance.length > 0 )
binding.attrs.relevant = '(' + relevance[relevance.length-1] + ')';

Because when you create a field list group (maybe only a group) it will add the previos relevance of a question and it has some troubles when you show the information.

And example without fix:
< bind nodeset="/data/Refresco/edad" type="select1"/>
< bind nodeset="/data/Refresco/edadanios" type="string" relevant="(/data/Refresco/edad=1)"/>
< bind nodeset="/data/Refresco/edadmeses" type="string" relevant="(/data/Refresco/edad=1) and (/data/Refresco/edad=2)"/>
without fix the second question wont appear.

And with the fix:
< bind nodeset="/data/Refresco/edad" type="select1"/>
< bind nodeset="/data/Refresco/edadanios" type="string" relevant="(/data/Refresco/edad=1)"/>
< bind nodeset="/data/Refresco/edadmeses" type="string" relevant="(/data/Refresco/edad=2)"/>

But I would like to know your opinion.

I tested with relevance group and this continues working.
Maybe with nested groups does not work, I didnt test it.

After this I'm trying to refresh the windows in the collect when a question has relevant in a fieldlist group, but this is another story =).

Looks like this was fixed with 5ee00d7.
