Partial fix for map pairs issue.

In MapPairs.java need to fins a solution for:
if (true/*this.getParentNode().getNodeName().equals("MapAnnotation")*/) {
so it can select the correct element to make.

There is also a problem with the mapAnnotation update template.
e.g. This cause a crash:
./bfconvert dummy\&annMap=3.fake fake2.ome
