Top BDII Publishing Revamp

I have updated the topbdii summary page.
It now includes an historical element as well so you can see the individual site inclusions in each top level BDII over a period of time. There are clearly some topBDIIs which are flakier than others represented by vertical blue lines and some sites are dropped at times by all BDIIs represented by horizontal blue lines.

Also the tables are broken down by BDII version numbers as well.
