Version 1.0 of biocache can not generate a list of layers to sample from the layerstore

This is a high priority issue because we can't dynamically generate a list of 
layers to use in a fully released versioned code base.

Issue is a regression  bug that was introduced here:

http://code.google.com/p/ala-portal/source/browse/trunk/biocache-store/src/main/
scala/au/org/ala/biocache/config.scala?spec=svn4402&r=4254

Not a critical bug because we can specify a CSV list of layers to work around 
this. But is is not the ideal fix because we will miss any new layers.

We also need to decide what this means to "Version 1.0". We can decide to do 
nothing about it because the layers are ala specific and shouldn't effect other 
users, and we have a work around.  I believe that we have already decided that 
the next version to be released to macropus will be a 1.1-SNAPSHOT. The issue 
will be if we leave it too long and new layers become available.

I have fixed it in the 1.1-SNAPSHOT.
