curentPageNode is not manage properly in navigation

[hduchesne]

<c:set var="curentPageNode" value="${jcr:getMeAndParentsOfType(renderContext.mainResource.node,'jnt:page')}"/> return an array but is not managed as his.

e.g. If I create this hierarchy Page Lvl0 -> Lvl1 -> Lvl2

if I add a navbar in Lvl2 and select currentPage as starting point, curentPageNode is equals to [node /sites/i8/lvl0/lvl1/lvl2, node /sites/i8/lvl0/lvl1, node /sites/i8/lvl0]

to fix this we have to check if currentPage is not empty and extract the first element

<c:if test="${fn:length(curentPageNode) > 0}">
    <c:set var="curentPageNode" value="${curentPageNode[0]}"/>
</c:if>

Why not this? <c:set var="curentPageNode" value="${renderContext.mainResource.node}"/>

I thought about it, but if mainRessource is not a page, we can be in trouble. after we can also do a test...

I closed this PR; the link for to parent page (site node) does not work. Maybe we should link to the homepage.
