A few updates since the catalog release

I got some feedbacks from the users of GMBCG cluster catalog ever since its public release. Especially, Heinz Andernach has carefully check the catalog and gave back many good suggestions and pointed out several close pair duplicates. Some of the duplicates are due to the input DR7 catalog, where they are just the same object but assigned with different objids. Some others are due to the percolation codes I am using that did not catch the very close pairs. Altogheter, there are 13 such BCGs are "duplicated". I removed them and updates all the catalogs(Fits and ascii). Now, the total # of clusters are 55,424.（The last update is on 11/14/10）
